Comment on If one day our Fingerprint ends up Getting Stollen, Is There a Way we can Change it?

Could you? Yes. But there really is no point— biometrics alone are only a single factor for authentication.

You should have at least two of the three— something you are (fingerprint, facial, or retinal recognition), something you have (badge, token, secure device), and something you know (passphrase).

    It really sucks when you’re told your code is too short to use.

biometrics alone are only a single factor for authentication.

I’d argue that biometrics is NOT an authentication factor but is instead a username. You’re identifying who you are.

  Authentication is, explicitly, the process of validating that you are who you say you are. Like biometrics, your username is part of your digital identity. So you are correct in arguing that biometrics alone is little stronger than a username, but by definition, both are part of authentication.
  
  That said, to securely authenticate your identity, you need to use multiple factors.
