How to use Face ID on the iPhone XSource: iMore

Face ID is Apple's latest biometric authorization system and the successor to Touch ID. And much like Touch ID, Face ID lets you not only unlock your phone or iPad Pro, but authorize Apple Pay payments, confirm iTunes and App Store Purchases, and to activate username and password autofill in Safari.

The TrueDepth camera system, which powers Face ID, also has a couple of tricks of its own based on the attention that you give to your phone.

Of course, to use any of these features, you'll first have to set up Face ID.

Here's how you can set things up to get the most out of Face ID on your supported iPhone or iPad Pro.

Which devices support Face ID?

As of March 2020, there are three generations of iPhone and two generations of iPad Pro that support Face ID.

How to manage attention features for Face ID

The TrueDepth camera, by default, will sense if you're actually looking at your iPhone when trying to unlock with Face ID, and your phone won't unlock if you're not. But these attention-aware features also go beyond unlocking your phone.

  1. Open Settings on your supported iPhone or iPad Pro.
  2. Tap Face ID & Passcode.
  3. Enter your passcode.

With "Attention Aware Features" turned on, the TrueDepth camera will check to see if you're looking at your iPhone before it dims your display or lowers the volume of alerts.
