Missing the point
Passwords (on a good day) identify someone who is authorised to access a facility. Bit like a door key. I can give a friend a door key and tell them to let themselves in if I'm not at home. I can give a (trusted) friend or relative my card and pin and ask them to get some cash out for me or to buy something for me. No need to identify who is actually doing this, the fact that they have the 'key' is sufficient.
Biometrics, in theory, identify individuals. I can't give my finger to a friend to let themselves in. (Well, I CAN, but I wouldn't really want to) - Biometrics are fundamentally effective for tracking the location and actions of individuals, even when completely unnecesaary. Very, very dangerous.
