Nextcloud with OpenID / social login - Calendar CalDAV Synchronization

TL;DR

💡 Create an app password in Nextcloud and use that.

Requirements​

  • Nextcloud with the social login app using Cloudron OpenID
  • the Nextcloud the calendar app
  • an urge to use the calendar in your favorite Client e.g. Thunderbird, mobile phone google calendar etc

CalDAV needs authentication (username and password). When logging in with Cloudron via OpenID, the User in Nextcloud has no "password" and cannot set one.

Obtain the CalDAV URL​

Get into your Nextcloud and copy your internal calendar url:

Step 1 - click your calendar​

top right corner - click the calendar symbol

Step 2 - share your calendar / view the calendar sharing information:​

click the link symbol on your calendar

Step 3 - Copy the internal link​

alt text

Link should look something like this:

https://YOUR.DOMAIN.TLD/remote.php/dav/calendars/my.DOMAIN.tld-USER.NAME/hackradt/

please note that hackradt is the name of the calendar.

Save this into a notepad, you will need it later.

Obtain credentials for your user​

Our user has no password. We have to set a Nextcloud app password.

Step 1 - click your user profile icon (top right)​

top right corner your profile button

Step 2 - click "personal settings" (in the dropdown menu)​

button with personal settings text

Step 3- click "security" (left side)​

button with security text

In the bottom of that page you got "Devices & sessions". Enter a new app name, I choose "SyncMyDav"

bottom left field enter SyncMyDav

Click "Create new app password" Note down the Username and Password and be 100% sure to click Done - if you forget the Done part it will not work!

Now you can use these credentials and the URL to configure your Thunderbird or DAVx⁵ for your Android phone.

Finally you can use your external Nextcloud with your Cloudron login, with en extra app password for your calendar.
