How Do I Add Another Face ID to My iPhone 13?

You can add an alternative appearance to your iPhone 13's Face ID, which essentially allows you to have two facial scans stored. Here's how:

1. Open the Settings app on your iPhone.
2. Scroll down and tap on "Face ID & Passcode".
3. Enter your passcode.
4. Look for the option "Set Up an Alternative Appearance". Tap on it.
5. Follow the on-screen instructions to scan your face. You'll be prompted to position your face within the frame and move your head as instructed.
6. Once the scan is complete, tap "Done".

Now you have successfully added an alternative appearance to your Face ID. This can be useful if you often wear glasses, change your hairstyle, or want to improve Face ID recognition under different lighting conditions. Keep in mind that you can only store one "Alternative Appearance".
