You can store a second face on your iPhone or iPad using the Face ID settings, and it works just like the first one

Your iPhone or iPad can recognize and unlock for two different faces. This is useful if you share a device with a family member, want a backup face registered, or need to set up Face ID for someone else who uses your phone regularly. The second face is stored with the same security as the first — it's not a weaker alternative, just an additional authorized user.

The process takes about two minutes and happens entirely in your device settings. You don't need a computer, an app, or any special equipment. Both faces must be real — you cannot add a photo, a mask, or a digital image.

Key Takeaways

  • Open Settings, tap Face ID & Passcode, enter your passcode, and select "Set Up an Additional Appearance" to add a second face.
  • Position your face in the circle on the screen and move your head slowly in a complete circle while the camera scans your face.
  • You will be asked to repeat the scan a second time to complete the setup.
  • Both faces unlock the device and authorize Apple Pay and App Store purchases with equal priority — there is no "primary" or "secondary" face.
  • If Face ID stops recognizing you after adding a second face, restart your device and try again.

Step-by-step: Adding the second face

Step 1: Open Settings and navigate to Face ID. Tap the Settings app on your home screen. Scroll down and tap "Face ID & Passcode." You will be asked to enter your device passcode. Type it in and tap the arrow or press Enter.

Step 2: Select "Set Up an Additional Appearance." After you enter your passcode, you will see a screen with options. Look for the text "Set Up an Additional Appearance" and tap it. This is the button that lets you add a second face. If you do not see this option, it means your device already has two faces registered, which is the maximum.

Step 3: Position your face in the circle. The camera will open and show a circle in the center of the screen. Hold your device at arm's length and position your face so it fits inside the circle. Make sure your face is well-lit — avoid backlighting or shadows across your eyes. The circle will turn green when your face is in the right position.

Step 4: Move your head in a slow circle. Once the circle turns green, slowly move your head in a complete circle — up, to the right, down, and to the left. Move at a steady pace, not too fast. The camera is mapping the shape of your face from different angles. You will see a progress bar at the bottom of the screen showing how much of the scan is complete.

Step 5: Complete the second scan. When the first scan finishes, the screen will say "Move your head to complete the circle" or similar text. Repeat the same slow circular motion. This second scan confirms the first one and makes Face ID more accurate. When both scans are done, you will see a "Face ID is now set up" message.

Step 6: Tap "Done." Press the Done button to close the setup screen and return to Face ID settings. Your second face is now registered and active.

What to do if the scan fails or gets stuck

If the camera cannot complete the scan, you will see an error message like "Move Closer" or "Face Not Detected." This usually means the lighting is poor, your face is too far away, or something is blocking the camera lens. Wipe the camera lens with a soft cloth and try again in a brighter room.

If the scan starts but freezes partway through, close the Settings app and try again. Press the home button or swipe up from the bottom of the screen to exit, then reopen Settings and start from Step 1. If this happens repeatedly, restart your device: hold the power button until you see the power-off slider, slide it, wait 30 seconds, then press the power button again to turn it back on.

If you see a message saying "Face ID is not available," your device may not support a second face, or there is a hardware issue with the camera. This is rare on newer iPhones and iPads, but older models may not have this feature.

How the second face works after setup

Once the second face is registered, both faces have equal priority. When you pick up your device, Face ID will unlock it if it recognizes either face — there is no "first" or "second" face that gets checked first. The unlock happens in the same instant regardless of which face is scanned.

The same applies to Apple Pay, App Store purchases, and any other action that uses Face ID. Both faces can authorize payments and downloads without any difference in security or speed. If you want to remove the second face later, go back to Settings, tap Face ID & Passcode, enter your passcode, and tap "Delete Face" next to "Additional Appearance."

Common mistakes to avoid

Do not wear glasses, sunglasses, or a hat during the scan unless you plan to always wear them when unlocking your device. Face ID learns what you look like during setup, so if you scan without glasses and then always wear glasses, the unlock may be slower or fail. If you wear glasses sometimes and not other times, you can set up Face ID both ways by adding a second appearance with glasses on.

Do not move your head too quickly during the scan. The camera needs time to map your face from each angle. If you rush through the circle, the scan may fail or be incomplete, and Face ID may not work reliably afterward.

Do not assume the second face is less secure. Both faces have the same level of protection. The device does not treat one as a backup or weaker option — it simply recognizes two authorized users.

When to use a second face instead of sharing your passcode

If someone in your household uses your device regularly, adding their face is more secure than giving them your passcode. With Face ID, they can unlock the device and use it, but they cannot change your passwords, access your email settings, or make purchases from your account without Face ID authorization. If you share your passcode, they have access to all of these.

A second face is also useful if you want a backup way to unlock your device. If you are injured or your appearance changes temporarily, having a second registered face means someone else can still unlock the device in an emergency. This is not a replacement for knowing your passcode — you should always remember your passcode as a backup — but it adds flexibility.

Frequently Asked Questions

Can I add more than two faces?

No. iPhones and iPads support a maximum of two faces. If you need to change which faces are registered, you must delete one before adding another. Go to Settings, Face ID & Passcode, enter your passcode, and tap "Delete Face" next to the face you want to remove.

Will adding a second face slow down Face ID?

No. Face ID recognizes both faces at the same speed. The unlock time does not change whether you have one face or two registered. The device checks both simultaneously, so there is no delay.

What if the second face is very similar to the first, like a twin?

Face ID may have trouble distinguishing between very similar faces. If you are setting up Face ID for a twin or close family member, the scan may occasionally unlock for the wrong person. This is a limitation of the technology, not a setup error. You can test this after setup by having both people try to unlock the device and see if Face ID works correctly for each.

Can I use a second face if I have a beard or facial hair that changes?

Yes. Face ID learns your face shape, not just your facial hair. Small changes like growing or shaving a beard should not prevent unlock. Major changes like shaving off a full beard might cause temporary slowness, but Face ID will adapt over time as it learns the new appearance.

What happens if I forget which face is registered?

Go to Settings, tap Face ID & Passcode, enter your passcode, and look at the screen. You will see "Face ID" and "Additional Appearance" listed. Tap each one to see which face is which — the app will show you a preview or description of each registered face. If you want to swap them, delete one and re-register it in the order you prefer.
