About this guide

The original documentation on which this guide is based was written and maintained by the development team at Nextcloud in Germany.

This documentation is relevant to the version of Nextcloud that has been used as part of the gE.CO toolbox (version 19). However, at the time of writing, the latest release of Nextcloud is version 22. This means that some things explained about Nextcloud elsewhere (such as online help guides) may be different in this version. In addition, this guide may not be relevant for other deployments of Nextcloud elsewhere (e.g. on other websites or servers).

This guide has been carefully edited to be relevant to users of the gE.CO toolbox. However, the original documentation on which this guide is based was written to explain all features and settings in Nextcloud 19. The gE.CO toolbox version may not have all of these features available. Settings such as storage space, applications and custom colours/styles can vary between realisations of Nextcloud, so please bear this in mind.

If you think an edit to this guide is required, please contact the gE.CO project team at Newcastle University.

What is Nextcloud?

Welcome to Nextcloud: A safe home for all your data.

Nextcloud is an open-source file sync and share software provided through the ge.CO toolbox. Nextcloud provides a safe, secure, and compliant file synchronisation and sharing solution on a server set up as part of the running of the gE.CO toolbox.

You can share one or more files and folders on your computer, and synchronise them with your Nextcloud server. Place files in your local shared directories, and those files are immediately synchronised to the server and to other devices using the Nextcloud Desktop Sync Client, Android app, or iOS app. To learn more about the Nextcloud desktop and mobile clients, please refer to their respective manuals in Nextcloud's documentation base:

New features in this version of Nextcloud

  1. Easier way to select a new app

  5. Many other improvements and new apps, like screensharing in Video calls, new Circles app for user defined groups, push notifications, notifications of file changes even when shared to another server, undo removal of files from a shared folder even if the removal was done by a recipient, directly sharing to social media and much more.

Accessing Nextcloud through the gE.CO toolbox

You can connect to Nextcloud via Navigate to Go to the services and press the Open service button beside the Nextcloud service you require.

Nextcloud login screen.

Web browser requirements

For the best experience with the Nextcloud web interface, we recommend that you use the latest and supported version of a browser from this list:

  • Microsoft Internet Explorer
  • Microsoft Edge
  • Mozilla Firefox
  • Google Chrome/Chromium
  • Apple Safari


If you want to use Nextcloud Talk, you need to run Mozilla Firefox 52+ or Google Chrome/Chromium 49+ to have the full experience with video calls and screensharing. Google Chrome/Chromium requires a additional plugin for screensharing.

Creating an account

To access Nextcloud through the gE.CO toolbox, you will first need to create an account.

Once you have navigated to Nextcloud through the gE.CO toolbox and selected your service, you will be presented with a log in screen. If you already have an account, this is where you enter your username/email or password. If you have not yet created an account, you have three options. You can:

  • Register via an email and verification link;
  • Log in with your Google account, or;
  • Log in with your Facebook account.

If you are registering via an email, select Register and then enter your email in the box. Once you have pressed Request verification link, check your emails for a link to finish creating your account with a username and password.

If you are logging in via Google or Facebook, you will be asked to enter your Google/Facebook account details. You may also be asked to allow Nextcloud access to your account details. These details are only used for the purposes of logging into Nextcloud, and it does not grant Nextcloud nor the administrators access to your accounts.

Each user of Nextcloud on the gE.CO toolbox has 2GB of storage space. A small amount of this will already be allocated for system data.

What you create, upload and store through your Nextcloud account will be only be accessible to you. It will also be accessible by the gE.CO toolbox administrators who control the server that powers Nextcloud, but administrators will not directly access your account.

Other users of Nextcloud cannot access your files or your data, unless you decide to share it with them through file sharing.

By default, the Nextcloud Web interface opens to your Files page. You can add, remove, and share files, and make changes based on the access privileges set by the administrator of Nextcloud. Please note that some features of Nextcloud may not yet have been made available for users of the gE.CO toolbox.

The main Files view.

The Nextcloud user interface contains the following fields and functions:

  • Apps Selection Menu (1): Located in the upper left corner, you’ll find all your apps which are available on Nextcloud. Clicking on an apps icon will redirect you to the app.
  • Apps Information field (2): Located in the left sidebar, this provides filters and tasks associated with your selected app. For example, when you are using the Files apps you have a special set of filters for quickly finding your files, such as files that have been shared with you, and files that you have shared with others. You’ll see different items for other apps.
  • Application View (3): The main central field in the Nextcloud user interface. This field displays the contents or user features of your selected app.
  • Navigation Bar (4): Located over the main viewing window (the Application View), this bar provides a type of breadcrumbs navigation that enables you to migrate to higher levels of the folder hierarchy up to the root level (home).
  • New button (5): Located in the Navigation Bar, the New button enables you to create new files, new folders, or upload files.


You can also drag and drop files from your file manager into the Files Application View to upload them. Currently, the only Web browsers that support drag-and-drop folders are Chrome and Chromium.

  • Search field (6): Click on the magnifier in the upper right hand corner of to search for files.
  • Contacts Menu (7): Gives you an overview about your contacts and users connected to your Nextcloud account. Dependent on the given details and available apps, you can directly start a video call with them or send emails.
  • Gallery button (8). This looks like four little squares, and takes you directly to your image gallery.
  • Settings menu (9): Click on your profile picture, located to the right of the Search field, to open your Settings dropdown menu. Your Settings page provides the following settings and features:
    • Personal info (includes profile picture, group memberships, storage space, language options and social media sharing buttons)
    • Security (includes passwords, two-factor authentication and managing connected browsers and devices)
    • Social media login with Google and Facebook
    • Activity (for notification settings)
    • Mobile & desktop (for downloads to other apps and calendar and contact integrations)
    • Accessibility (inlcuding high contrast, dark and dyslexia support options)
    • Sharing (for Federated Cloud and file ownership transfer options)
    • Flow (which allows you to write event information into a Nextcloud conversation)
    • Privacy (which indicates how your data on Nextcloud is being used and who has access to it)
    • Collabora Online (which allows you to specify a directory for templates on the Collabora integration)

See the Setting your preferences section to learn more about these settings.

Files and synchronisation

Accessing your files

You can access your Nextcloud files with the Nextcloud Web interface and create, preview, edit, delete, share, and re-share files.

The Files view screen.

Tagging files

You can assign tags to files. To create tags, open a file to the Details view. Then type your tags. To enter more than one tag press the return key after creating each tag. All tags are system tags, and are shared by all users.

Creating file tags.

Then use the Tags filter on the left sidebar to filter files by tags:

Viewing file tags.


Use the Details view to add and read comments on any file or folder. Comments are visible to everyone who has access to the file:

Creating and viewing comments.

Video player

You can play videos in Nextcloud with the Video Player app by simply clicking on the file. Video streaming by the native Nextcloud video player depends on your Web browser and the video format. See this guide for supported multimedia formats in Web browsers.

Watching a movie.

File controls

Nextcloud can display thumbnail previews for image files, MP3 covers, and text files. Hover your cursor over a file or folder to expose the controls for the following operations:

  • Favourites

    Click the star to the left of the file icon to mark it as a favorite:Marking Favorite files.

    You can also quickly find all of your favorites with the Favourites filter on the left sidebar.

  • Overflow Menu

    The Overflow menu (three dots) displays file details, and allows you to rename, download, or delete files:Overflow menu.The Details view shows Activities, Sharing, and Versions information:

Details screen.

The Settings gear icon at the lower left allows you to show or hide hidden files in your Nextcloud Web interface. These are also called dotfiles, because they are prefixed with a dot, e.g. .mailfile. The dot tells your operating system to hide these files in your file browsers, unless you choose to display them. Usually these are configuration files, so having the option to hide them reduces clutter.

Hiding or displaying hidden files.

Previewing files

You can display uncompressed text files, OpenDocument files, videos, and image files in the Nextcloud embedded viewers by clicking on the file name. There may be other file types you can preview too. If Nextcloud cannot display a file, it starts a download process and downloads the file to your computer.

Navigating through folders in Nextcloud is as simple as clicking on a folder to open it and using the back button on your browser to move to a previous level. Nextcloud also provides a navigation bar at the top of the Files field for quick navigation.

Sharing status icons

Any folder that has been shared is marked with the Shared overlay icon. Public link shares are marked with a chain link. Unshared folders are not marked:

Share status icons.

Creating or uploading files and directories

Upload or create new files or folders directly in a Nextcloud folder by clicking on the New button in the Files app:

The New file/folder/upload menu.

The New button provides the following options:

  • Up arrow

    Upload files from your computer into Nextcloud. You can also upload files by dragging and dropping them from your file manager.

  • Text file

    Creates a new text file and adds the file to your current folder.

  • Folder

    Creates a new folder in the current folder.

Selecting files or folders

You can select one or more files or folders by clicking on their checkboxes. To select all files in the current directory, click on the checkbox located at the top of the files listing.

When you select multiple files, you can delete all of them, or download them as a ZIP file by using the Delete or Download buttons that appear at the top.

Filtering the files view

The left sidebar on the Files page contains several filters for quickly sorting and managing your files.

  • All files

    The default view; displays all files that you have access to.

  • Favourites

    Files or folders marked with the yellow star.

  • Shared with you

    Displays all files shared with you by another user or group.

  • Shared with others

    Displays all files that you have shared with other users or groups.

  • Shared by link

    Displays all files that are shared by you via public link.

  • External Storage (optional)

    Files that you have access to on external storage devices and services such as Amazon S3, SMB/CIFS, FTP, etc.

Moving files

You can move files and folders by dragging and dropping them into any directory.

Federated Cloud Sharing allows you to mount file shares from remote Nextcloud servers, and manage them just like a local share. See Using Federation Shares to learn to how to create and connect to new Federated Cloud shares.

Using WebDAV

Nextcloud fully supports the WebDAV protocol, and you can connect and synchronise with your Nextcloud files over WebDAV (which stands for Web Distributed Authoring and Versioning).

Please refer to the Nextcloud documentation for how to use this feature. You can also contact gE.CO toolkit support if you need any help in using this feature.

Managing deleted files

When you delete a file in Nextcloud, it is not immediately deleted permanently. Instead, it is moved into the trash bin. It is not permanently deleted until you manually delete it, or when the Deleted Files app deletes it to make room for new files.

Find your deleted files by clicking on the Deleted files button on the Files page of the Nextcloud Web interface. You’ll have options to either restore or permanently delete files.


Deleted files are not counted against your storage quota. Only your personal files count against your quota, not files which were shared with you. See Storage quota to learn more about quotas.

What happens when shared files are deleted

Deleting files gets a little complicated when they are shared files, as this scenario illustrates:

  1. User1 shares a folder “test” with User2 and User3
  2. User2 (the recipient) deletes a file/folder “sub” inside of “test”
  3. The folder “sub” will be moved to the trashbin of both User1 (owner) and User2 (recipient)
  4. But User3 will not have a copy of “sub” in their trash bin

When User1 deletes “sub” then it is moved to User1’s trash bin. It is deleted from User2 and User3, but not placed in their trash bins.

When you share files, other users may copy, rename, move, and share them with other people, just as they can for any computer files; Nextcloud does not have magic powers to prevent this.

How the deleted files app manages storage space

To ensure that users do not run over their storage quotas, the Deleted Files app allocates a maximum of 50% of their currently available free space to deleted files. If your deleted files exceed this limit, Nextcloud deletes the oldest files (files with the oldest timestamps from when they were deleted) until it meets the memory usage limit again.

Nextcloud checks the age of deleted files every time new files are added to the deleted files. By default, deleted files stay in the trash bin for 30 days, but the gE.CO toolbox administrator can adjust this value. Files older than this will be deleted permanently. Additionally, Nextcloud calculates the maximum available space every time a new file is added. If the deleted files exceed the new maximum allowed space Nextcloud will expire old deleted files until the limit is met once again.


Contact gE.CO toolkit support if you need files kept for longer than 30 days.

Desktop and mobile synchronisation

For synchronising files with your desktop computer, we recommend using the Nextcloud Sync Client for Windows, macOS and Linux.

The Nextcloud Desktop Sync Client enables you to connect to Nextcloud on the gE.CO toolbox. You can create folders in your home directory, and keep the contents of those folders synced with Nextcloud. Simply copy a file into the directory and the Nextcloud desktop client does the rest. Make a change to the files on one computer, it will flow across the others using these desktop sync clients. You will always have your latest files with you wherever you are.

Its usage is documented separately in the Nextcloud Desktop Client Manual.

Mobile clients

Visit your Personal page in your Nextcloud Web interface to find download links for Android and iOS mobile sync clients. Or, visit the Nextcloud download page.

Encrypting your Nextcloud files

Nextcloud includes a server side Encryption app, which can enable all of your Nextcloud data files to be automatically encrypted on the server.

Please contact gE.CO toolkit support if you wish to make use of this feature.

File Sharing

Nextcloud users can share files and folders. Possible targets are:

  • public links
  • users
  • groups
  • circles
  • talk conversations
  • users or groups on federated Nextcloud servers

You can share files and folders via public links.

A random 15-digit token will be created. The link will look like

A number of options are available for public folder shares:


  • Read only to allow viewing and downloading
  • Allow upload and editing
  • With File drop, the sharee can only upload files to a folder without seeing the files that are already in that folder.
  • Hide download prevents the sharee from downloading
  • Password protect
  • Set expiration date will automatically disable the share
  • Note to recipient
  • Unshare to revert the share
  • Add another link to create multiple public links with different rights

For public file shares, you may allow editing the file with one of Nextcloud’s collaborative editing solutions.



In this version of Nextcloud, Password protection and file expiration are not available using Federated File Sharing.

Internal shares with users and groups

When sharing with users, groups, circles or members of a Talk conversation, rights for the files or folder contents are adjustable:


As a sharee, you can configure if you automatically want to accept all incoming shares and have them added to your root folder, or if you want to be asked each time if you want to accept or decline the share.


For adjusting the acceptance setting, go to Settings > Personal > Sharing


Others with access

In order to find out if a file or folder is accessible to others through sharing of a superior folder hierarchy level, click on Others with access in the sharing tab.


The list shows all users, groups, chats etc. that the current object has been given access to through sharing of a superior folder in the hierarchy.


Click on the three dots to

  • see who initiated the share
  • see where the share was initiated (click to navigate to the folder, as far as you have access there)
  • unshare the initial share (only accessible for the share owner)


This information is only visible to the owner of a file/folder or sharees with resharing rights.

Federated Shares

Federation Sharing allows you to mount file shares from remote Nextcloud servers (for example, those run by another organisation or collective). In effect, this creates your own cloud of Nextclouds. You can create direct share links with users on other Nextcloud servers.

Creating a new Federation Share

Federation sharing is enabled by default. Follow these steps to create a new share with other Nextcloud or ownCloud servers:

Go to your Files page and click the Share icon on the file or directory you want to share. In the sidebar enter the username and URL of the remote user in this form: <username>@<nc-server-url>. In this example, that is


The sharee is receiving a notification in their Nextcloud, allowing them to either accept or decline the incoming share.


Adding a public share to your Nextcloud

Nextcloud public link share pages offer an option to add that file or folder as a federated share into Nextcloud on the gE.CO toolbox. Just enter your <username>@<nc-server-url> just like shown for outbound shares above:


Making anonymous uploads

You may create your own special upload directories so that other people can upload files to you without having a log in for Nextcloud through the gE.CO toolbox, and without being a Nextcloud user. They will not be allowed to see the contents of this directory, or to make any changes. This is an excellent alternative to sending large attachments via email or using commercial file-sharing services.

Setting up your own file drop

Go to Files and create or choose the folder, the anonymous upload should be made to.


Check Share Link, Allow editing, Hide file listing.


Now you can send the link to the upload folder.

Uploading files

Using the anonymous upload function is simple. You receive a link to the upload folder, click the link, and then you’ll see a Nextcloud page with a “Click to upload” button.


This opens a file picker, and you select the file or directory you want to upload. You’re also able to just drop files into the window.

When your upload is completed, the filenames are listed:


Larger file uploads

Uploading files through the web client may be limited to smaller file sizes because of how Nextcloud is programmed. If you experience any difficulties in uploading files, please contact gE.CO toolbox support.

Storage quota

Your Nextcloud admin has the option to set a storage quota on users. With users of the gE.CO toolbox, this is currently 2GB. This figure is being regularly reviewed by administrators based on usage. Look at the top of your Personal page to see how much of this quota you have used.


It may be helpful to understand how your quota is calculated.

Metadata (thumbnails, temporary files, cache, and encryption keys) takes up about 10% of disk space, but is not counted against user quotas. Some apps store information in the database, such as the Calendar and Contacts apps. This data is excluded from your quota.

When other users share files with you, the shared files count against the original share owner’s quota. When you share a folder and allow other users or groups to upload files to it, all uploaded and edited files count against your quota. When you re-share files shared with you, the re-share still counts against the quota of the original share owner.

Encrypted files are a little larger than unencrypted files; the unencrypted size is calculated against your quota.

Deleted files that are still in the trash bin do not count against quotas. The trash bin is set at 50% of quota. Deleted file aging is set at 30 days. When deleted files exceed 50% of quota then the oldest files are removed until the total is below 50%.

When version control is enabled, the older file versions are not counted against quotas.

If you create a public share via URL and allow uploads, any uploaded files count against your quota.

Version control

Nextcloud supports simple version control system for files. Versioning creates backups of files which are accessible via the Versions tab on the Details sidebar. This tab contains the history of the file where you can roll back a file to any previous version. Changes made at intervals greater than two minutes are saved in data/[user]/files_versions.


To restore a specific version of a file, click the circular arrow to the left. Click on the timestamp to download it.

The versioning app expires old versions automatically to make sure that the user doesn’t run out of space. This pattern is used to delete old versions:

  • For the first second, we keep one version
  • For the first 10 seconds, Nextcloud keeps one version every 2 seconds
  • For the first minute, Nextcloud keeps one version every 10 seconds
  • For the first hour, Nextcloud keeps one version every minute
  • For the first 24 hours, Nextcloud keeps one version every hour
  • For the first 30 days, Nextcloud keeps one version every day
  • After the first 30 days, Nextcloud keeps one version every week

The versions are adjusted along this pattern every time a new version gets created.

The version app never uses more that 50% of the user’s currently available free space. If the stored versions exceed this limit, Nextcloud deletes the oldest versions until it meets the disk space limit again.


Users can associate files, chats and other items with each other in projects. The various apps will present these items in a list, allowing users to immediately jump to them. Projects are Nextcloud wide. When a user shares a file that is part of a project, the share recipient can see that project, too. A click on any of the items in a project leads right to it, be it a chat, a file or a task.

Create a new project

A new project can be created by linking two items together. Start off by opening a file or folders sharing sidebar.


Click Add to a project and select the type of item you want to link with the current file/folder. A selector will open that allows you selecting a Talk conversation for example.


Once the item has been selected a new project is being created and listed in the sharing tab of the sidebar. The same project will also appear in the sharing sidebar of the linked items.


The list entry shows quick links to a limited number of items. By opening the context menu, the project can be renamed and the full list of items can be expanded.

Adding more entries to a project

If another item should be added to an already existing project this can be done by searching for the project name in the Add to a project picker.


Visibility of projects

Projects do not influence the access and visibility of the different items. Users will only see projects of other users if they have access to all contained items.

Transfer Ownership

Users can transfer the ownership of files and folders to other users. Share ownerships of those transfered files/folders will also be transferred.

  1. Navigate to Settings > Personal > Sharing > Files.

  2. Click on Choose file or folder to transfer >> A file picker opens, showing all files and folders in the user’s account.

  3. Pick a file or folder and click on Choose >> The chosen file or folder name gets displayed.

  4. Click on Change to change the choice if necessary.

  5. Pick a new owner by typing their name into the search field next to New owner.

  6. Click on Transfer.

  7. The target user receives a notification where they are being asked whether to accept or reject the incoming transfer.


  8. If accepted, the target user finds the transferred files and folders in their root under a folder Transferred from [user] on [timestamp].

  9. The source user gets informed about the acceptance or rejection by a notification.

Calendar and Contacts

Nextcloud comes with various productivity apps to help teams with collaboration. This is refered to as Groupware in the Nextcloud User Manual. In this section, we describe how to use the Calendar and Contacts apps in the gE.CO toolbox.

The Calendar and Contacts apps use CalDAV/CardDAV with the respective web interfaces.

Nextcloud also includes Deck, a project management tool which allows you to create Kanban-style task boards and share them with your team.

You can find out more about Nextcloud Groupware on Nextcloud's website.

Using the Contacts app

The Nextcloud Contacts app is similar to other mobile contact applications, but with more functionality. Let’s run through basic features that will help you maintain your address book in the application.

Below, you will learn how to add contacts, edit or remove contacts, upload a contact picture and manage your Contact app address books.

Adding Contacts

When you first access the Contacts app, an empty default address book becomes available.


Default Address Book (empty)

To add contacts into your address book, you can use one of the following methods:

  • Import contacts using a Virtual Contact File (VCF/Vcard) file
  • Add contacts manually

The fastest way to add a contact is to use a Virtual Contact File (VCF/Vcard) file.

Importing Virtual Contacts

To Import Contacts Using a VCF/Vcard File:

  1. Find “Settings” at the bottom of the left sidebar, next to the gear button.

    Contact settings gear button

  2. Click the gear button. The Contacts app “Import” button will appear.

    Contacts Upload Field


The Contacts app only supports import of vCards version 3.0 and 4.0.

  1. Click the “Import” button and upload your VCF/Vcard file.

After the import is complete, you will see your new contact in your address book.

Adding Contacts Manually

If you can’t import virtual contacts, the Contacts app enables you to add contacts manually.

To Create a New Contact:

  1. Click the + New contact button.

    An empty new contact configuration opens in the Application View field.


  1. Specify the new contact information. Changes that you made are implemented immediately.

Edit or Remove Contact Information

The Contacts app enables you to edit or remove contact information.

To edit or remove contact information:

  1. Navigate to the specific contact that you want to modify.
  2. Select the information in the field that you want to edit or remove.
  3. Make your modifications or click on the trash bin.

Changes or removals that you made to any contact information are implemented immediately.

Contact Picture

To add a picture for your new contacts, click on the upload button:

Contact picture (upload button)

After you have set a contact picture, it will look like this:

Contact picture (set)

If you want to upload a new one, remove it, view it in full size or download it, click on the contacts picture for the following options to appear:


Adding and Managing Address Books

Clicking on the “Settings” (gear) button at the bottom of the left sidebar provides access to Contact app settings. This field shows all available address books, certain options for each address book, and enables you to create new address books, simply by specifying an address books name.

Add address book in the contacts settings

The Contacts settings is also where you can share, export and delete address books. You will find the CardDAV URLs there.

See below for more details about syncing your address books with Android devices, Apple devices and other programs that use CardDAV.

Using the Calendar app

The Nextcloud Calendar app works similar to other calendar applications you can sync your Nextcloud calendars and events with.

When you first access the Calendar app, you will be presented with a blank interface. You can fill this up quickly by adding meetings, and eventually your calendar may look something like the image below.


Managing your calendars

Import a Calendar

If you want to transfer your calendar and their respective events to your Nextcloud instance, importing is the best way to do so.


  1. Click on the settings-icon labeled with Settings & Import at the left-bottom.
  2. After clicking on + Import Calendar you can select one or more calendar files from your local device to upload.
  3. The upload can take some time and depends on how big the calendar you import is.


The Nextcloud Calendar application only supports iCalendar-compatible .ics-files, defined in RFC 5545.

Create a new Calendar

If you plan to setup a new calendar without transferring any old data from your previous calendar, creating a new calendar is the way you should go.


  1. Click on + New Calendar in the left sidebar.
  2. Type in a name for your new calendar, e.g. “Work”, “Home” or “Studies”.
  3. After clicking on the checkmark, your new calendar is created and can be synced across your devices, filled with new events and shared with your friends and colleagues.

Edit, Download or Delete a Calendar

Sometimes you may want to change the color or the entire name of a previous imported or created calendar. You may also want to export it to your local hard drive or delete it forever.


Please keep in mind that deleting a calendar is a irreversible action. After deletion, there is no way of restoring the calendar unless you have a local backup.


  1. Click on the three-dot-menu of the respective calendar.


  1. Click on Edit, Download or Delete.

Sharing calendars

You may share your calendar with other users or groups. Calendars may be shared with write access or read-only. When sharing a calendar with write access, users with whom the calendar is shared will be able to create new events into the calendar as well as edit and delete existing ones.


Calendar shares currently can’t be accepted or rejected. If you want to stop having a calendar that someone shared with you, you can click on the 3-dot menu next to the calendar in the calendar list and click on “Unshare from me”.

Publishing a calendar

Calendars can be published through a public link to make them viewable (read-only) to external users. You may create a public link by opening the share menu for a calendar and clicking on « + » next to « Share link ». Once created you can copy the public link to your clipboard or send it through email.

There’s also an « embedding code » that provides an HTML iframe to embed your calendar into public pages.

On the public page, users are able to get the subscription link for the calendar and download the whole calendar directly.

Subscribe to a Calendar

You can subscribe to iCal calendars directly inside of your Nextcloud. By supporting this interoperable standard (RFC 5545) we made Nextcloud calendar compatible to Google Calendar, Apple iCloud and many other calendar-servers you can exchange your calendars with, including subscription links from calendar published on other Nextcloud instances, as described above.

  1. Click on + New Subscription in the left sidebar.
  2. Type in or paste the link of the shared calendar you want to subscribe to.

Finished. Your calendar subscriptions will be updated regularly.


Subscriptions are refreshed every week by default. This setting can be changed by contacting gE.CO support.

Managing Events

Create a new event

Events can be created by clicking in the area when the event is scheduled. In the day- and week-view of the calendar you just click, pull and left your cursor over the area when the event is taking place.


The month-view only requires a single click into the area of the specific day.


After that, you can type in the event’s name (e.g. Meeting with Lukas), choose the calendar in which you want to choose the event (e.g. Personal, Work), check and concretize the time span or set the event as all-day event.

If you want to edit advanced details such as the Location, a Description, Attendees, Reminders or to set the event as a repeating-event click on the More...-button to open the advanced sidebar-editor.


If you always want to open the advanced sidebar-editor instead of the simple event editor popup, you can set a Skip simple event editor-checkmark in the Settings & Import-section of the app.

Clicking on the blue Create-button will finally create the event.

Edit or Delete an event

If you want to edit or delete a specific event, you just need to click on it. After that you will be able to re-set all event details and open the advanced sidebar-editor by clicking on More.

Clicking on the Update-button will update the event. To cancel your changes, click on the close icon on top right of the popup or sidebar editor.

If you open the sidebar view and click the three dot menu next to the event name, you have an option to export the event as an .ics file or remove the event from your calendar.


Invite attendees to an event

You may add attendees to an event to let them know they’re invited. They will receive an email confirmation and will be able to confirm or cancel their participation to the event. Attendees may be other users on your Nextcloud instances, contacts in your addressbooks and direct email addresses. You also may change the level of participation per-attendees, or disable email confirmation for a specific attendee.



When adding other Nextcloud users as attendees to an event, you may access their Free/Busy information if it’s available, helping you to determine when is the best time slot for your event.

Only the calendar owner can send out invitations, the sharees are not able to do that, whether they have write access to the event’s calendar or not.

Setup Reminders

You can set up reminders to be notified before an event occurs. Currently supported notification methods are :

  • Email notifications
  • Nextcloud notifications

You may set reminders at a time relative to the event or at a specific date.



Only the calendar owner and people or groups with whom the calendar is shared with write access will get notifications. If you don’t get any notifications but think you should, please contact gE.CO support.


If you synchronise your calendar with mobile devices or other 3rd-party clients, notifications may also show up there.

Add recurring options

An event may be set as “recurring”, so that it can happen every day, week, month or year. Specific rules can be added to set which day of the week the event happens or more complex rules, such as every fourth Wednesday of each month.

You can also tell when the recurrence ends.


Birthday calendar

The birthday calendar is an auto-generated calendar which will automatically fetch the birthdays from your contacts. The only way to edit this calendar is by filing your contacts with birthday dates. You can not directly edit this calendar from the calendar-app.


If you do not see the birthday calendar, please contact gE.CO support.

Using two-factor authentication

Two-factor authentication (2FA) is a way to protect your Nextcloud account against unauthorised access. It works by requiring two different ‘proofs’ of your identity. For example, something you know (like a password) and something you have like a physical key. Typically, the first factor is a password like you already have and the second can be a text message you receive or a code you generate on your phone or another device (something you have).

You can enable and configure two-factor authentication in Setting your preferences. Below you can see how.

Configuring two-factor authentication

In your Personal Settings look up the Two-Factor Authentication setting. In this example this is TOTP, a Google Authenticator compatible time-based code.

TOTP configuration.

You will see your secret and a QR code which can be scanned by the TOTP app on your phone (or another device). Depending on the app or tool, type in the code or scan the QR and your device will show a login code which changes every 30 seconds.

Recovery codes in case you lost your 2nd factor

You should always generate backup codes for 2FA. If your 2nd factor device gets stolen or is not working, you will be able to use one of these codes to unlock your account. It effectively functions as a backup 2nd factor. To get the backup codes, go to your Personal Settings and look under Second-factor Auth settings. Choose Generate backup codes.

2FA backup code generator

You will then be presented with a list of one-time-use backup codes.

2FA backup codes

You should put these codes in a safe spot, somewhere you can find them. Don’t put them together with your 2nd factor like your mobile phone but make sure that if you lose one, you still have the other. Keeping them at home is probably the best thing to do.

Logging in with two-factor authentication

After you have logged out and need to log in again, you will see a request to enter the TOTP code in your browser. If you enable not only the TOTP factor but another one, you will see a selection screen on which you can choose two-factor method for this login. Select TOTP.

Choosing a two-factor authentication method.

Now, just enter your code:

Entering TOTP code at login.

If the code was correct you will be redirected to your Nextcloud account.


Since the code is time-based, it’s important that your server’s and your smartphone’s clock are almost in sync. A time drift of a few seconds won’t be a problem.

Using two-factor authentication with hardware tokens

You can use two-factor authentication based on hardware tokens. The following devices are known to work:

Using client applications with two-factor authentication

Once you have enabled 2FA, your clients will no longer be able to connect with just your password unless they also have support for two-factor authentication. To solve this, you should generate device specific passwords for them. See Manage connected browsers and devices for more information on how to do this.


If you use WebAuthn to login to your Nextcloud be sure to not use the same token for 2FA. As this would mean you are again only using a single factor.

Manage connected browsers and devices

The personal settings page allows you to have an overview on the connected browsers and devices.

Managing connected browsers

In the list of connected browsers you see which browsers connected to your account recently:

List of browser sessions.

You can use the trash icon to disconnect any of the browsers in the list.

Managing devices

In the list of connected devices you see all the devices and clients you generated a device password for and their last activity:

List of connected devices.

You can use the trash icon to disconnect any of the devices in the list.

At the bottom of the list you find a button to create a new device-specific password. You can choose a name to identify the token later. The generated password is used for configuring the new client. Ideally, generate individual tokens for every device you connect to your account, so you can disconnect those individually if necessary.

Adding a new device.


You have only access to the device password when creating it, Nextcloud will not save the plain password, hence it’s recommended to enter the password on the new client immediately.


If you are using two-factor authentication for your account, device-specific passwords are the only way to configure clients. The server will deny connections of clients using your login password then.

Device-specific passwords and password changes

For password changes in external user backends, the device-specific passwords are marked as invalid, and once a login of the user account with the main password happens, all device-specific passwords are updated and work again.
