Re: Not a positive use
Using facial recognition to obsolete passwords is a very very bad thing. I have helped people with their iPhone X and to unlock it, I once just held up to his face. The phone was in my hand and I was able to unlock it. Imagine this scenario: The police arrest you and they want to get into your phone. They don't need a warrant because all they have to do is hold up to your face. Now they are in and can do whatever they want.

US courts have held that even in circumstances where they can't demand your password or that you unlock a device, they can demand that you apply your finger to a fingerprint reader thus unlocking a device.
