Hi J=C3=B6rg,
IMO, biometric was a gimmick in the first place and a bad idea when
carefully considered. All authenticators can be compromised. Hence, all
authenticators must be replaceable following a compromise. If one of your
DCs' palm vein databases is lost, what's your plan for replacing that hand?
Basic two or three factor authentication: something that you know
(password), something that you are (biometric) and something that you have
(access card).
You can tell your password to a coworker but he can not borrow your hand.
Hence you need both. The password is the replaceable part.
