Advanced unlocking/biometrix unlocking with multiple fingers #1038

I would really like to use advanced unlocking. Typing a long masterpassword over and over is very tedious. However, fingerprint logins have been shown to be unsave.

So the questions is, would it be possible to have a multiple fingerprint unlocking mechanism where you need to validate 2 or more fingers in a given period of time to unlock the keefile?

I would feel much saver with this and would consider using it.

I doubt it because biometrics are transparently handled by the operating system. Also, I question the point of this feature because 10x unsafe is still unsafe. If someone has access to one fingerprint, most-likely he has access to all of them. What could be implemented is a check for a password plus a biometric feature.

As @cbiere says, the recognition is done by API of the system, technically it would require cascading keys into the Keystore and unlocking them several times but there is no real point in doing that.
