They are password replacements in most contexts. The point of a password is usually just to verify your identity. Biometrics can do that just fine.

- charonn0 10y agoBiometrics are good replacements for usernames, but not for passwords. Biometrics can't be changed in the event of a breach, and can be taken from you surreptitiously or by force.
- 794CD01 10y agoYes, and those features are not necessary in most scenarios passwords are currently used.
- infogulch 10y agoBiometrics can be fooled, and even if they couldn't they can only verify your identity. They can't verify your volition.
- 794CD01 10y agoThey can be fooled now, but that is an implementation flaw, not a problem with the concept. I wouldn't cite the weakness of unsalted MD5 hashes as a problem with the concept of passwords. I agree with your assessment of what biometrics can and cannot do. That is why I specifically said that in most situations, passwords are only used to verify someone's identity, and thus can be replaced with biometrics.
