To unlock your device using Face ID, simply glance at it. You may 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.
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.
