Why Is Face ID Not Working?

Face ID allows for easy unlocking of the screen. If it fails to work, you could miss a lot, including authenticating purchases, signing in to apps, etc., and might wonder, why is my Face ID not working? Below is why:

  • You've put on a face mask, yet you never set up Face ID while wearing a mask.
  • Your iPhone has rebooted or was off and got switched on.
  • You had not unlocked the iPhone for 48+ hours.
  • You have neither used the iPhone's passcode in the last 6½ days nor the Face ID feature in the last 4 hours.
  • You have already attempted five unsuccessful Face ID matches.
  • You started the power off/Emergency SOS by long pressing either of the volume buttons and the Power button simultaneously for 2 seconds.
  • Your iPhone has a software issue or you downloaded corrupted files hence the Face ID not working after update error.
  • Something might be blocking the camera, or you are in a not well-lit place.
  • Your iPhone doesn't support Face ID technology, as it only works for iPhone X and later models.
  • You are using an outdated iOS version.
  • The iPhone has received a remote lock command.

Take Off Your Sunglasses or Mask

To ensure FaceID can recognize you, your eyes, nose, and mouth should be fully visible. Sunglasses block infrared rays and affect the TrueDepth sensor from working. However, if you must wear a face-covering such as a mask, you can set up a Face ID to ensure the feature will recognize you.


  1. Open Settings.
  2. Go to Face ID & Passcode and enter your passcode.
  3. Toggle on Face ID With a Mask.
  4. On the next page, choose the Use Face ID With a Mask option.
  5. Remove your mask and set up your Face ID.
  6. Use Face ID with a mask


  • This feature is only available on iPhone 12 or later.
  • If you wear glasses in daily life or when using a mask, make sure to wear them while setting up Face ID with a Mask.
  • You can tap the Add Glasses option in Face ID & Passcode to set up Face ID to work with sunglasses or regular glasses.

Hold Your iPhone Correctly

Why is my Face ID not working? Face ID only works efficiently if you hold it in portrait orientation. Additionally, don't hold the iPhone too far away or too close to you. It could be the reason why Face ID is not working on your iPhone.


  1. Go to screen lock.
  2. Hold your iPhone 10-20 inches from your face.
  3. Swipe up to unlock.
  4. Hold iPhone in a portrait position.

Note: On supported iPhone models like iPhone 13 and 14 running iOS 16, Face ID is able to work in Landscape mode, making it easier to unlock the ‌iPhone‌ when it's not held in the standard Portrait orientation.

Check the Face ID Settings

Before diving into deeper fixes, it's best to try the basic checks. Probably, Face ID was never enabled, or it was recently disabled, or someone else erased your face. Here's how to check:


  1. Go to Settings > Face ID & Passcode. If you don't see this option, your iPhone doesn't have Face ID installed.
  2. If asked, enter Passcode.
  3. If you see Reset Face ID, you have already set up Face ID. Otherwise, follow the prompts to set it up now.
  4. Ensure the options for iPhone Unlock, iTunes & App Store, Wallet & Apple Pay, and Password AutoFill are enabled.

Note: If you see Set Up Face ID in blue letters, you either never set up Face ID to begin with or someone erased your face. To fix the problem, just click Set Up Face ID.

Check Face ID Permission

Some third-party apps such as banking and instant messaging might require Face ID authentication to log in. So, if you denied an app permission to use Face ID, you will need to enter your iPhone passcode each time instead. You can ensure Face ID is enabled for a supported third-party iPhone app.


  1. Open Settings and scroll down to find the listed third-party apps. .
  2. Select the specific app.
  3. Toggle on Face ID.

Note: You can access the complete list of apps that have requested Face ID access by going to Settings > Face ID & Passcode > Other Apps.

Toggle on Face ID permissions

Reset Face ID

Though the last resort, you can completely reset your Face ID and set it up again. It will erase all previous scans you 've made to unlock your iPhone. It might be worth starting all over again, especially if it gets your Face ID working again.


  1. Go to Settings.
  2. Tap Face ID & Passcode.
  3. Enter the passcode if prompted, then tap Reset Face ID.
  4. Reset Face ID.
  5. Tap Set Up Face ID.
  6. Hold your device in portrait position and tap Get Started.
  7. Slowly move your head to complete the circle. Tap Accessibility Options if you're unable to move your head.
  8. When the first Face ID scan is complete, tap Continue.
  9. Slowly move your head to complete the circle again.
  10. When the Face ID setup is complete, tap Done.
  11. Complete Face ID scan.

Reboot your iPhone once you're done setting up your new Face ID then try to see if it's already working as intended.
