iOS 16 App Store Face ID is a biometric authentication system that allows users to unlock their iPhone or iPad and make purchases in the App Store using their face. It uses the TrueDepth camera system to create a detailed 3D map of the user’s face, which is then used to verify their identity. Face ID is more secure than Touch ID, as it is more difficult to spoof a face than a fingerprint.
Face ID was first introduced with the iPhone X in 2017. It has since been added to all new iPhone and iPad models. Face ID is a convenient and secure way to unlock your device and make purchases. It is also used to authenticate Apple Pay transactions and to sign in to apps.
