New for iOS 12: How to Allow a Second Person to Use Face ID on Your iPhone X, XS, XS Max or XR

* This post is part of iPhone Life's Tip of the Day newsletter. . *

Apple has offered biometric locking features since it introduced Touch ID with the iPhone 5s. With the iPhone X, biometric authentication took the leap to Face ID, and that feature is also included in Apple's newest iPhones, the iPhone XS, XS Max, and XR. There's a convenient new feature with the latest operating system, iOS 12, that allows facial recognition for not just one, but two people. Now if you'd like to share your iPhone with a partner, friend, or child, you don't have to give them your passcode or open the phone yourself before handing it to them. Let's get started setting your iPhone X and later to recognize a second face.
