biometrics will still require a fallback for any general purpose system. For example, you can't require fingerprints because there's a chance you'll get users without fingers. You can't require retinal scans because there's a chance you'll get users without eyes. You could probably ask the user to spit and check their DNA, but there's a higher chance of spreading disease that way. Eventually you'll need a fallback of a password/key, and if I were an attacker, I'd always attack the fallback (it's often the least well thought out part of auth).
