1. What is Face ID and How Does It Work

Face ID is a facial recognition system designed and developed by Apple for iOS devices.  The Face ID hardware consists of a sensor, a laser dot projector, a flood illuminator, and an infrared TrueDepth camera. The whole system can project a grid of small infrared dots onto a user's face, shine infrared light at the face, take an infrared picture of the user, read the resulting pattern, and build a 3D facial map. The iOS built-in system will compare this map with the face that the user registered before and authenticate whether it's the same face.

2. How to Set Up Face ID

It is wise to enable the secure Face ID feature on your iPhone to unlock a device, make payments, view sensitive or important data, and perform detailed facial expression tracking for Animoji and other services when you are required for authentication on your device. It's also quite easy to set up your Face ID. Here's how:

Step 1. On your iPhone, go to Settings > Face ID & Passcode. Enter your passcode to verify your identity.

Step 2. Select Set Up Face ID > Get Started.

Step 3. Position your face inside the frame and move your head to adjust the circle. When you finish the first Face ID scan, tap Continue.

Step 4. Move your head to complete the circle for a second time. Tap Done to dismiss it.

3. Can Someone Unlock Your Phone with Face ID While Sleeping

Can you unlock an iPhone with Face ID with your eyes closed? No. People can't unlock an iPhone using its owner's face when he/she is sleeping because users are required to open their eyes and look at the device screen to attempt a face match.

When you perform a face recognition action, the Face ID technology generates a 3D map of your face to match. The system can recognize faces with glasses, clothing, makeup, beard, and mask. (Mask-compatible Face ID is available on iPhone 12 and later devices). In addition, the Face ID technology is so advanced and cutting-edge that you don't need to worry if it still can recognize your face as the same one when you change in appearance over time.
