How can I enable my face recognition again

Hello!

To enable FaceID on your iPhone X or newer:

1. Open Settings
2. Scroll down to FaceID and Passcode
3. If you haven't set a passcode, select "Turn Passcode On" and set a Code
4. Select "Set Up Face ID"
5. Follow the instructions to set up
6. Choose what you want to "Use Face ID for". You can use FaceID for Unlocking your phone, making iTunes and App Store purchases, paying using Apple Pay and the Wallet App, or Filling in Password with iCloud Keychain.

If you have an iPhone 12 or newer, and your iOS version is updated to 15.4 or later, you are able to use FaceID while wearing a mask. You will be asked if you will be using Face ID with a mask when setting it up.

Here's some relevant help articles:
