Apple reveals how its controversial Face ID system works

In mid-September, Apple unveiled its new Face ID facial recognition system, which is due to debut with the iPhone X on Nov. 3. The system lets users unlock their phones just by glancing at them, but has also raised privacy questions and some anxieties over whether someone could force you to unlock your phone by pointing it at your face. Now, Apple has revealed an in-depth explanation of how the system works - and has admitted young users may struggle.
