Hello @bytepartner
Please see: https://docs.cloudron.io/packages/vikunja
With the config file you can control e.g.: self-registration (which is disabled by default when using the Cloudron user management).
As far as I know, Vinkunja does not have Admin accounts, you will have to use the vinkunja cli => https://vikunja.io/docs/cli/
You can open the Web Terminal of your Vinkunja Cloudron app and just do e.g.:
vikunja user create --help
Create a new user.
Usage:
vikunja user create [flags]
Flags:
-a, --avatar-provider string The avatar provider of the new user. Optional.
-e, --email string The email address of the new user.
-h, --help help for create
-p, --password string The password of the new user. You will be asked to enter it if not provided through the flag.
-u, --username string The username of the new user.
