Google can't kill passwords, they can simply make it more convenient to login for users like TouchID. Biometrics should simply be an additional part of 2 factor authentication. Finger prints are something we have, passwords are something we know. Police or criminal or a partner could simply put your thumb on your phone to login into it without your consent (or knowledge if you are asleep). Where is people without arms, hands or lose or damage them later in life wouldn't work. Passwords are compromised all the time but you can simply change it. If your fingerprint is stolen eventually you have no realistic option to change it. Biometrics should simply be an additional layer of security as it is today.
