With iOS 12 Face ID can be recorded in two different faces!

With iOS 12, it is possible to record a second face in Face ID, which is the biometric screen lock of the iPhone X. So you do not have to tell people you often share your device.

With the iPhone X, Apple bid farewell to Touch ID and offered the use of Face ID, which scans the face of the user in three dimensions. Face ID technology is very practical and safe, but you had to tell the password of the screen lid to entrust a reliable second person phone because you could scan a single user's face.
