Can You Unlock Face ID While Sleeping?

From iPhone X to the later models, Apple has been using Face ID instead of Touch ID for unlocking its iPhone. This new facial recognition technology offered a more secure and convenient way to unlock iOS devices, sign in to apps, authenticate purchases, and more.

However, have you ever wondered if you can unlock Face ID while sleeping? Or rather, do you know how to unlock Face ID while sleeping? These are questions many users have thought about since this technology was introduced and so did people at Apple.

Part 1. Can Face ID Work While Asleep?

You won’t unlock Face ID if you’re sleeping because your eyelids would be closed yet Face ID requires eye contact for it to function. It detects the eyes and then checks whether they’re opened or not, and from there it unlocks the iPhone. Therefore, if you’re sleeping, someone has to open your eyelids in order to unlock your Face ID while sleeping, which is highly unlikely. As such, we can certainly conclude that it’s not possible to unlock Face ID while sleeping for the fact that the system needs to detect the face as well as the eyes for it to work.

The Technology Behind Face ID

Face ID utilizes an advanced facial recognition technology that Apple calls the “TrueDepth camera system”. This system comprises multiple light projectors and sensors that it uses to take multiple pictures of your facial features which it then stores them so that it can compare them when needed. It generally captures a 3D map of the face, plus the camera utilizes Infrared Light when taking the pictures, which means Face ID is able to work anywhere, anytime.
