With iOS 12, you can now add multiple faces to Face ID on your iPhone X. All thanks to a new option called Alternative Appearance under Face ID settings on iOS 12.

The alternative appearance feature is probably meant to add a second appearance of yourself to the Face ID. But as it turns out, you can add a whole new Face to your iPhone X’s Face ID using this new feature on iOS 12.

How to add multiple faces to Face ID on iPhone X

  1. Open Settings.
  2. Go to Face ID & Passcode settings.
  3. Scroll down a bit, and tap Set Up an Alternative Appearance.
  4. Register a second Face to your iPhone X.

That’s it.
