3 Face ID Security
Touch ID isn’t dead quite yet. Both the iPhone 8 and the iPhone 8 Plus will retain a Home button and Apple’s fingerprint-based authentication system. The iPhone X, on the other hand, won’t have a Home button or Touch ID — and instead will rely on Face ID, Apple’s new advanced facial recognition system.
It relies on a neural engine and infrared sensors, so it works in the dark, and will adapt to a user’s face over time (if they change hairstyles or grow a beard, for example). It’s faster and more secure, too. Apple said that Touch ID has about a 1 in 50,000 chance of false authentication. With Face ID, that stat drops to 1 in 1,000,000. And it won’t be easily spoofed by a picture of you.
