Face ID’s Innovation: Continuous Authentication

I believe Face ID is slower at actual recognition than Touch ID, but it’s nearly impossible to notice due to the implementation. In the time it takes to move your finger to the Touch ID sensor, Face ID could have already unlocked your iPhone.

That’s the real Face ID revolution. Since you’re almost always looking at your phone while you’re using it, Face ID enables what I call “continuous authentication.”
