Face ID is a newer technology being implemented into smartphones so users can unlock their device using their face. This technology was put into the recent iPhone X, which came out earlier this year. Apple’s hope is that it is good enough to replace the fingerprint scanner, since the home button was taken away in this years iPhone. According to Forbes, Customers don’t seem to mind the loss of the fingerprint scanner, judging by the skyrocketing sales of the iPhone X.

Face ID uses a combination of light projectors and sensors to take several images of your facial features using the True Depth Camera System in the device. This advanced camera system allows the phone to recognize you instantly. A big part of Face ID is registering the users eyes. Because the eye is such a detailed area of the face, it makes Face ID very secure. Unlike the fingerprint sensor, Face ID can only store one face, where the fingerprint sensor can store up to five at a time. Face ID is much more secure than the fingerprint sensor, and is a step in the right direction for smartphone security.
