Authelia is an authentification provider. So you can have a single login for all your services. It can provide autorisation and authentification with a single unified login.

Bitwarden is much “simpler”, in it’s just a passwordmanager. As soon as you start sharing passwords, like you do in bitwarden, you lose the authentification part, even worse, you lose control over the shared login. Anyone with autorisation can “steal” the login as in unauthorized copying/distributing the password or even changing the password alltogether.

With an sso like authelia you can mitigate such attack vectors.

Quick heads up, Nextcloud works perfectly fine behind an auth provider. I am using it behind authentik.

Blaming bad usability/lack of features on the user is just what it: a bad excuse.

For completeness, we cannot say for sure if we even exist. The universe could very well just be an imagination and nothing really matters, including the laws of physics and our understanding of magnets.

Also, it doesn’t feature a serial port. This phone is almost useless. /s
