Face ID is supposed to be more secure than Touch ID. It’s not. In fact it’s no more secure than a 4 digit code. Here’s how... Pick up your mate's iPhone X. Try to authenticate using FaceID. You can’t. Now look what happens. You simply need to input their security code (could be 4 digits) to gain full access to the phone. Apple could make FaceID 2 a hundred times more secure in iOS 12 but if it falls back to a 4 digit code it’s irrelevant. Never thought about it until tonight when a mate demonstrated it to me in the local pub!!!
