I've added this to #5251 for now

I'd like to understand better what we shell achieve by adding this? Bitwarden is a password storage solution, but nextcloud itself has a very good solution for that allready integrated as app, that can import passwords from bitwarden pretty well. What problem does bitwarden solve in context of nextcloud aio?

[szaimen]

The main reason is that an external password solution might be more reliable then then integrated one which is very important for passwords imho.
