I dont agree with many things apple does at all, and I also think their password manager has flaws like revealing usernames without authentification.
It is pretty handy though, to have a file where the entries are stored unencrypted, and if the password manager detects an entry it prompts to decrypt exactly that field, maybe with a fingerprint.
KeepassDX needs to run in the background and be completely unlocked to even detect apps or password fields.
Do you know any existing app that can do this?
The official docker image uses a lot more resources than the vaultwarden container, but it allows significantly more than 100 users. If it’s just for yourself and your family I suggest just going with Vaultwarden.
Why would any private person need this?
You don’t. I meant to say that only large organizations need the official Bitwarden docker setup, but I did not communicate that clearly enough.
