Un punto di vista condivisibile di Dustin Kirkland: le impronte digitali sono più adatte ad essere utilizzate come username, che password. Non solo una volta che vengono compromesse non possono essere cambiate, ma le lasciamo anche ovunque:
I could see some value, perhaps, in a tablet that I share with my wife, where each of us have our own accounts, with independent configurations, apps, and settings. We could each conveniently identify ourselves by our fingerprint. But biometrics cannot, and absolutely must not, be used to authenticate an identity. For authentication, you need a password or passphrase. Something that can be independently chosen, changed, and rotated. Once your fingerprint is compromised (and, yes, it almost certainly already is, if you’ve crossed an international border or registered for a driver’s license in most US states and many countries), how do you change it?
