Everything You Need To Know About Apple Face Id
EVERYTHING YOU NEED TO KNOW APPLE FACE ID
How it works:
The Apple's camera system is made up of several components, as you can see in the picture below. Working in tandem, the sensors and components project 30,000 infrared dots onto your face, which are then used to get all the curves and wrinkles on your face.
During initial setup of Face ID, that map is converted to a 2D image that the iPhone uses as a master key to unlock your device any day, any time.
Every time you wake up the screen of your iPhone, dots are projected, your face is mapped, and it's compared to the master key created during the Face ID setup. If it matches, your iPhone unlocks. If not, you're asked to try again or enter a passcode to unlock the device.
When it's used:
The most common use case for Face ID is unlocking your iPhone. Even though you tap on the display while your phone is sitting on your desk or you bring the phone up to view notifications, Face ID is activated and attempting to verify it's you looking at the phone or about to use your IPhone.
Notice the Face ID logo at the bottom of the screen? Whenever you see it, Face ID is actively trying to scan your face.
Outside of unlocking your iPhone, Face ID can also be used to:
Authorize Apple Pay:
Approve purchases in the IPhone App Store, iTunes, iBooks
Sign into third-party apps such as data or password managing apps
Another cool feature about Face ID is that when your appearance changes slightly -- say your hair is done differently or you shaved your beard -- Face ID might fail. However, when you enter your passcode after Face ID failed to recognize you, it uses that scan to teach itself that your appearance has changed slightly and next time it should recognize you without issue which is very cool. Right??
When configuring up your iPhone XS (or XS Max, XR or X) for the first time, you'll be asked if you want to use Face ID. If you chose not to, you can still enable Face ID through the Settings app later on.
To register your face with Face ID, hold your phone between 10 and 20 inches away from your face. With your face centered in the circle, move your head around until the scan is complete. It's easiest to slowly move in a circle. You'll be asked to complete a second scan, after which Face ID setup will be complete.
