Adding an account

Select Tasks settings > Synchronization > Add account > CalDAV and enter the following details:

• User for authentication with your CalDAV server
• Password for authentication with your CalDAV server
  • Android 6+: Passwords will be encrypted with the Android KeyStore
  • Android 4 and 5: Passwords will be stored in plain text
• URL to your CalDAV home set
  • Tasks will follow the /.well-known/caldav redirect for URLs that use SSL. As an example you can enter https://my.owndrive.com and Tasks will find your home set
  • For servers that do not provide a redirect you will need to enter the home set URL yourself. This URL will vary by server, but will look something like https://example.com/remote.php/caldav/calendars/myusername/
• Server type
