Rich Mogul, writing for Securosis:
Apple didn’t just throw a facial recognition sensor into the iPhone and replace a fingerprint sensor – they enabled a new security modality. I call this “continuous authentication”.
I’ve been thinking about it ever since getting the new iPhone X. The way Apple implemented integration between parts of iOS and FaceID shows a level of attention to detail unseen in other companies, and a great security design overall.
