We used an infrared camera to show how the iPhone X's FaceID actually works

The iPhone X has a new way to unlock your phone. It's called Face ID. When it recognizes your face, it unlocks.

Inside the notch at the top is the TrueDepth camera and sensors. This camera projects over 30,000 dots onto your face. The dots are invisible to your eyes. But you can see them through an infrared camera. The iPhone X's camera analyzes the dots on your face and compares it to the image made when Face ID was set up. If they match, the phone unlocks.

Face ID can adapt to sunglasses, scarves, and hats. It also adjusts to changes in appearance - like shaving. Apple says Face ID has a 1 in 1,000,000 chance of being fooled. We tried tricking Face ID with twins, but Face ID wasn't fooled.

Apple also built an extra layer of security into the phone. Pressing the Power button 5 times will disable Face ID. This forces you to unlock the phone with a password.
