Authentication != authorisation.

The bank manager is still authentically the bank manager, gun or not.

Identity != authentication. The bank manager is, from the identification POV, still the bank manager. The bank manager may not be intending to authenticate, though.

I think you're splitting hairs. Authentication simply means to verify someone being who they claims they are. No more, no less.

If we go by your definition login with id and password isn't authentication either. How would we know if the person is "intending to authenticate"!

The bank manager is identified, but the request is not authenticated.
