Android Question Encrypt / Decrypt string with fingerprint authentication


Is there a way to decrypt a string with fingerprint authentication ?
I have an encrypted file that can be decrypted with a password. I want to encrypt the password and get back a decrypted string by using fingerprint authentication.
is it possible ?
You don't get access to the key itself.
That's a little bit disterbing.
Is there a way to get to the key ? because most password manegers apps today gives you an option to get to the database with biometric authntication and if it is not possible to get to the key it means that they are saving the raw password somewere in the app database !!!
