Without an iota of doubt, Face ID is the biggest highlight of iPhone X. To me, its a revolutionary feature and primed not just to make smartphone even smarter but also change the way we look at facial recognition technology. Considering how significant this advanced feature is, it's apt to make a complete guide on how to set up and use Face ID on iPhone X.

According to Apple, the odds that someone else' fingerprint will unlock Touch ID are 1 in 50,000, while Face ID's chance of another face matching is just 1 in 1,000,000. As no visible light is used, the scan is invisible in all lighting conditions. To avoid unintentional unlocking, facial recognition is made to be “attention aware.” What's more, it is also used in various lighting conditions, including dark rooms.
