Apple first introduced Face ID to the iPhone in 2017 with the iPhone X. Though it was somewhat contentious at first (there was a lot of FUD about whether or not it was secure), a lot of Apple fans have come around to Face ID as a replacement for Touch ID (though some would argue both would be even better).
Face ID uses biometric authentication for unlocking a device, making payments, and accessing sensitive data. It uses your device's TrueDepth camera to scan your face using depth mapping to gather your face's details. With a full scan of your face, you can lock down your iPhone or iPad Pro so that your face is the only thing that can unlock it without knowing your passcode.
