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.

Imposter syndrome is real

Swiss here, Blick is known for low quality news. This “news” is only a claim from some unknown party. Very likely inaccurate or even plain wrong.

While being the cheapest, AC is also the type of heating with the least amount of comfort, while the most expensive solution, underfloor or wall heating is the best comfort. Radiant heat is much less intrusive than blowing air around violently.

You’re also wrong. Mainly, It has to do with the thermal capacity/mass of the building and not with differences in insulation values.

There are pros and cons for all building types.
