The TrueDepth camera has a similar range of view as when you take a photo or make a FaceTime call with the front camera. Face ID requires that the TrueDepth camera sees your face or your eyes, whether your device is lying on a surface or you're holding it in a natural position. To unlock your device using Face ID, simply glance at it. You might do this during the initial set up process, or at a later time by going to Settings > Face ID & Passcode. To start using Face ID, you need to first enroll your face. With iOS 15.4 and iPhone 12 or later, Face ID even works with face masks. Furthermore, it's designed to work indoors, outdoors, and even in total darkness. Face ID is designed to work with hats, scarves, glasses, contact lenses, and many sunglasses. If there is a more significant change in your appearance, like shaving a full beard, Face ID confirms your identity by using your passcode before it updates your face data. A portion of the neural engine of the A11, A12 Bionic, A12X Bionic, A13 Bionic, A14 Bionic, and A15 Bionic chip-protected within the Secure Enclave-transforms the depth map and infrared image into a mathematical representation and compares that representation to the enrolled facial data.įace ID automatically adapts to changes in your appearance, such as wearing cosmetic makeup or growing facial hair. The TrueDepth camera captures accurate face data by projecting and analyzing thousands of invisible dots to create a depth map of your face and also captures an infrared image of your face. The technology that enables Face ID is some of the most advanced hardware and software that we’ve ever created. Learn which iPhone and iPad models support Face ID. Apps that support Touch ID automatically support Face ID.

Developers can also allow you to use Face ID to sign into their apps. You can use it to authorize purchases from the iTunes Store, App Store, and Book Store, payments with Apple Pay, and more. With a simple glance, Face ID securely unlocks your iPhone or iPad Pro. Face ID provides intuitive and secure authentication enabled by the state-of-the-art TrueDepth camera system with advanced technologies to accurately map the geometry of your face.

In the same way that Touch ID revolutionized authentication using a fingerprint, Face ID revolutionizes authentication using facial recognition. Much of our digital lives are stored on iPhone and iPad, and it's important to protect that information. Learn how Face ID helps protect your information on your iPhone and iPad Pro.
