Feature description

Add more optional advanced security features as (a) auto-logoff after a certain time and (b) use of two factors (fingerprint and code) to login.

Why do you want this feature?

Passwords include very sensitive data like access to your bank and email account.
(A) Just fingerprint to log in is not very secure but comfortable. On the other side, having a long code is secure, but uncomfortable. Easier would be if one can set up fingerprint AND a (short) code to login, or better, a passphrase.
(B) There should be an auto-logoff so that the app gets blocked after a certain time (and not only after the mobile phone logged off).
(C) If possible, certain passwords could be more secured like others. Bitwarden has such a functionality, where for certain passwords one has to enter the master passphrase again.

Additional information

Is there any mechanism that the app or mobile phone gets blocked after a certain number of false logins?

I hope I am not blind and one or some of these features are integrated already.

The issue names no files, tests, or entry points. Start by reviewing the app's existing login, biometric authentication, session timeout, and password-lock behavior, then clarify which security feature is in scope. Done would require an agreed design and implementation criteria for the selected feature.
