Face ID is one of the flagship features of the iPhone X. The new facial recognition system beams more than 30,000 invisible dots onto a users face to build a unique facial map, which an infrared camera reads, captures an infrared image, then sends the data to the Secure Enclave in the A11 Bionic chip to confirm a match.
According to Apple, the A11 Bionic chip within the iPhone X uses machine learning to recognise changes in the users appearance meaning putting on glasses, wearing a hat or grow a beard won’t spoof the device. – Once iPhone X matches the users face, the device will unlock, authenticate purchases and reveal notifications and messages.
When setting up the iPhone X for the first time users are encourage to set up Face ID, however for those who skip the step or wish to turn it on at a later date, here’s how to setup Face ID on the iPhone X…
1) Open the Settings app on your iPhone X, select the Face ID & Passcode button. – From here you can choose to setup Face ID for the first time or reset your existing saved face.
2) Tap the ‘Set Up Face ID’ button which will take you to a camera screen with a circular frame. Your iPhone will ask you to turn your head in a circular motion while the device maps your face.
3) Once you have done the circular motion once, the device will ask you to do it for a second time and you will see the camera frame begin to light-up green which shows which angles of your face the iPhone as successfully mapped.
4) After you have completed the steps above, your iPhone will take you to a screen to say your Face ID setup process has been successful. – Unlike Touch ID that lets you enroll up to five fingers, Face ID only allows one registered face.
Alongside Face ID users must also create a passcode to act as a back-up. Persuades can be changed within the Face ID & Passcode screen.
