If you want to add a second person to your iPhone's Face ID recognition, iOS 12 now lets you do just that. Here's how.

Apple calls this feature adding an "alternate appearance," so technically, it's aimed at users who potentially wear various headgear for their job throughout the day, like safety equipment. However, you can use it to add another person to your iPhone's Face ID repertoire.

To do this, start by opening up the Settings app.

Scroll down and select "Face ID & Passcode."

Enter your passcode to continue.

Next, tap on "Set Up an Alternate Appearance."

Tap on "Get Started" at the bottom.

The person you're adding will go through the Face ID scan process like you do when you first set up your iPhone.

Once complete, hit "Done" at the bottom.

And that's all there is to it! The second person you added will immediately be able to unlock your phone using their face. Of course, even without their face added to Face ID, they can also still enter in your passcode if they know it.
