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?
Why not? I have my own instance running on my NAS and I love to have it self-hosted because this way I keep the passwords where I know nobody else can get them.
Because a password manager is critical and if you ask me I’d say no. If you have the know how and understand the risk you won’t be asking
