iPhone Unlock With Mask Not Working? Fixes

If your iPhone won’t unlock with Face ID while you’re wearing a mask, the fix is to update to iOS 15.4 or later and enable the “Face ID with a Mask” option, which works on iPhone 12 and newer models. For older iPhones or when that setting isn’t available, you’ll need to rely on your passcode, an Apple Watch, or a mask that exposes your face’s unique features.

Why Face ID Struggles With Masks

Face ID maps the unique geometry of your face using a dot projector and infrared camera. A mask physically covers key identifying areas—your nose, mouth, and parts of your cheeks—so the depth map no longer matches the enrolled face. Apple’s first response was to make Face ID learn a “partial face” by prompting you to unlock with your passcode while wearing a mask, but that only worked if the mask was loose enough to expose your eye region clearly. The real solution arrived with iOS 15.4, which uses the unique area around your eyes to authenticate, even when the rest of your face is covered.

How to Enable Face ID With a Mask

This feature is only available on iPhone 12, iPhone 13, iPhone 14, and newer models (including the iPhone SE 3rd generation). If you have one of these, follow these steps:

1. Go to Settings → Face ID & Passcode.
2. Enter your passcode.
3. Toggle on Face ID with a Mask.
4. If prompted, follow the on-screen instructions to re-scan your face. You may need to remove your glasses if you wear them, and you can add a second appearance for glasses later.

Once enabled, Face ID will work with most masks, including surgical, N95, and cloth masks. It works best when your eyes and the area around them are clearly visible. If you wear sunglasses, you’ll need to add them as a second appearance or disable the “Require Attention” setting.

What to Do If It Still Fails

If you’ve enabled the setting but Face ID still fails, try these troubleshooting steps in order:

• Update iOS: Make sure you’re on iOS 15.4 or later. Older versions don’t have the mask feature.
• Re-enroll your face: Go to Settings → Face ID & Passcode → Reset Face ID, then set it up again. This often improves accuracy, especially if you’ve grown a beard or changed your hairstyle.
• Check mask position: Pull the mask up higher so it sits closer to your nose bridge. If it’s too low, it might cover part of your eye area.
• Try without glasses: If you wear glasses, remove them and see if Face ID works. If it does, add a second appearance with the glasses on.
• Restart your iPhone: A simple restart can clear temporary software glitches.

If none of these help, your iPhone may not support the mask feature (iPhone 11 and earlier), or your mask might be too thick or dark to allow the infrared camera to see your eyes clearly.

Using an Apple Watch to Unlock

If your iPhone is older or you prefer not to enable the mask setting, you can use an Apple Watch to unlock your iPhone while wearing a mask. This works on iPhone 11 and later with watchOS 7.4 or later. To set it up:

1. On your iPhone, go to Settings → Face ID & Passcode.
2. Toggle on Unlock with Apple Watch.
3. Make sure your Apple Watch is on your wrist, unlocked, and has a passcode enabled.

When you try to unlock your iPhone with Face ID while wearing a mask, the watch will vibrate and notify you that the iPhone was unlocked. You can also use this to approve Apple Pay and App Store purchases, but not for password autofill in third-party apps.

Common Misconceptions and Limitations

Many users believe that Face ID with a mask works with any mask, but it actually requires the area around your eyes to be visible. Full-face masks, balaclavas, or masks with thick eye coverings will still fail. Also, the feature doesn’t work with sunglasses unless you add a second appearance. Another misconception is that the mask setting reduces security—Apple claims it uses the unique structure around your eyes, which is still highly secure, but it’s slightly less accurate than full-face scanning. If you’re concerned about security, you can keep the setting off and use a passcode.

Alternatives for Older iPhones

If you have an iPhone 11 or earlier, you don’t have access to the mask feature. Your options are:

• Use a passcode: The most reliable method, though less convenient.
• Use an Apple Watch: As described above, works on iPhone 11 and later.
• Try a mask that exposes your nose: Some masks with a clear plastic panel over the mouth can help Face ID see more of your face, but results vary.

There is no official way to enable mask unlock on unsupported iPhones without jailbreaking, which is not recommended for security and stability reasons.

Frequently Asked Questions

Does Face ID with a mask work with all mask types?

It works with most common masks—surgical, cloth, N95—as long as your eyes and the bridge of your nose are visible. It won’t work with full-face masks, balaclavas, or masks that cover your eyes.

Why doesn’t my iPhone have the “Face ID with a Mask” option?

This option is only available on iPhone 12 and newer models. If you have an older model, you won’t see it in Settings. Also, make sure you’ve updated to iOS 15.4 or later.

Can I use Face ID with a mask and sunglasses?

Yes, but you need to set up a second appearance with the sunglasses on. Go to Settings → Face ID & Passcode → Set Up an Alternate Appearance, and scan your face while wearing the sunglasses.

Is Face ID with a mask less secure?

Apple states that the probability of a false match is 1 in 1,000,000 with full-face Face ID. With the mask feature, it’s slightly higher, but still very secure. The system uses the unique features around your eyes, which are difficult to spoof.

What should I do if Face ID with a mask works sometimes but not always?

Try re-enrolling your face, ensure your mask is positioned correctly, and check that your iPhone’s camera lens is clean. If you wear glasses, try adding an alternate appearance with them on. If the problem persists, restart your iPhone or reset Face ID entirely.
