Applewith the release of the in November 2017, replacing the Touch ID fingerprint sensor with Face ID. The new True Depth camera on all new models since then, and the latest , for approving purchases, unlocking your phone and signing into apps.
Normally you set up Face ID the first time you turn on your phone, but if you or the sales rep skipped past it, take a couple of minutes to set it up and secure your phone. Seriously, it takes no time and it locks down all of the personal information you store on your phone.
Register your face
Set up Face ID by opening the Settings app and going to Face ID & Passcode > Set Up Face ID > Get Started. You'll be asked to enter a passcode that will be used as a fallback authentication method should Face ID not recognize you, when restarting your device, or when it hasn't been unlocked in the last 48 hours.
Register your face by holding your phone 10 to 20 inches (25 to 50 centimeters) in front of you, centering your face within the circle shown on the screen. Rotate your head in a circular motion until the white lines on the outside of the circle turn green. You'll need to scan your face twice. You don't have to move your head in a circular motion, but it does speed up the process and make it easier.
During setup, Face ID collects 30,000 points of data as a map of your face. From now on, when you unlock your phone or approve an Apple Pay purchase, that map will be used to identify you.
Unlocking your phone or tablet is now as simple as waking the screen while you're looking at it. Face ID usually works fast enough that by the time the screen is fully on, you just need to swipe up from the bottom of the lock screen and your home screen will be waiting for you.
