Apple today confirmed the iPhone X will feature facial recognition technology dependent upon a new “true depth camera system” including an infrared camera, flood illuminator, dot projector, and proximity sensor.
The Face ID feature will work in low light situations and, according to Apple, there’s only a one-in-a-million chance another face can unlock your device, unless you have an evil twin (according to Apple, if you do have an evil twin you should use passcode security).

Every time you look at your iPhone X, it detects your face. The feature will allow users to unlock devices simply by looking at their phones and swiping up, essentially letting iPhone owners to use their face as a password.
The device features a built-in neural engine to perform the computational heavy lifting required to process users’ faces. This allows the iPhone X to learn your face and increase security. It will also enable to the device to compensate for things like changing your hair color, growing a beard, or getting glasses.
The Face ID feature will work with Apple Pay, and has third party developer support as well. It’ll be interesting to see how the technology is used in non-Apple apps.
