Not really. Most biometric authentication systems are pretty poor. Add that to the fact that most biometric systems don't use very many features of the signal (e.g. they don't have a lot of key strength / entropy) and you get a pretty lame authentication systems.
A hardware key, on the other hand, can be almost arbitrarily big, is upgradable and totally random.

- rm999 14y agoI assume the phone would be the hardware key and the fingerprint would be an additional security measure because people are more likely to lose/misplace their phones.
