Face ID Not Working on iPhone? Here’s How to Fix It

Start by wiping the front camera area with a clean, soft cloth and removing any case or screen protector that overlaps it. Hold the iPhone in front of your face at a natural distance, make sure your eyes, nose, and mouth are visible, and try again. Then open Settings > Face ID & Passcode and confirm that Face ID is set up and enabled for iPhone Unlock, purchases, Wallet, passwords, or the affected app.

If those checks do not work, restart the iPhone, update iOS, add an alternate appearance if appropriate, or reset Face ID and enroll your face again. When setup repeatedly fails, Face ID is disabled, or the TrueDepth camera does not work, Apple recommends arranging service.

Which iPhones Support Face ID?

Face ID first appeared on iPhone X and is available on most later full-screen iPhone models. The iPhone SE line uses Touch ID instead, and older Home-button iPhones do not contain the TrueDepth system required for Face ID.

Open Settings and look for Face ID & Passcode. If the iPhone only shows Touch ID & Passcode, it uses fingerprint authentication. Follow the separate fixes for Touch ID not working on iPhone.

Face ID is not a normal selfie-camera feature. It depends on multiple components in the TrueDepth camera system, including infrared technology that maps facial depth. A selfie camera that takes photographs successfully does not prove that every Face ID component is functioning.

Why Is Face ID Not Working?

Common causes include:

• A smudge over the TrueDepth camera
• A case or protector obstructing the sensor area
• The iPhone being too close, too far away, or poorly angled
• Eyes, nose, or mouth being covered
• Sunglasses blocking infrared light
• Face ID with a Mask not being configured
• The wrong Face ID feature being disabled in Settings
• Five unsuccessful recognition attempts
• A restart or security event requiring the passcode
• Temporary iOS or app problems
• Major changes in appearance
• A damaged or uncalibrated front-camera system
• Display or camera repair performed incorrectly

Work through the following fixes in order. Skip directly to the physical-damage section when the problem began immediately after a drop, liquid contact, or repair.

When Face ID Is Not Actually Broken

iOS sometimes requires the passcode even when Face ID is working correctly. This protects the device and biometric data.

The passcode may be required:

• After restarting or turning on the iPhone
• When the iPhone has not been unlocked for an extended period
• After several unsuccessful Face ID attempts
• After Emergency SOS is activated
• After remotely locking the device
• When opening Face ID & Passcode settings
• Before updating a facial scan or changing security settings

Enter the passcode, lock the iPhone, and test Face ID again. If it recognizes you on the next normal unlock, there may be no fault.

Some apps also require their password or PIN after an update, sign-out, account change, or security timeout. Face ID cannot bypass an app’s deliberate reauthentication requirement.

1. Clean the TrueDepth Camera Area

Use a clean, soft, lint-free cloth to wipe the top of the display around the notch or Dynamic Island. Remove fingerprints, makeup, skin oil, dust, and moisture.

Avoid:

• Spraying cleaner directly on the iPhone
• Using abrasive material
• Pushing liquid into the speaker or sensor openings
• Scraping dirt with a pin or sharp tool
• Applying excessive pressure to a cracked display

The camera area can look clean while a thin layer of oil affects the infrared system. Test Face ID immediately after wiping it.

If the display is cracked across the camera area, use the passcode and arrange inspection rather than pressing or cleaning aggressively.

2. Remove the Case and Screen Protector

A poorly fitted case, privacy protector, camera cover, or thick screen protector can overlap the TrueDepth camera or interfere with infrared light.

Remove the accessories and test Face ID again. Pay particular attention to:

• Protectors that were designed for a different model
• Dust trapped around a notch or Dynamic Island cutout
• A protector that has shifted
• Cracks or bubbles over the sensor area
• Sliding webcam privacy covers
• Cases with raised edges near the front camera

If Face ID works with the accessory removed, replace it with one designed for the exact iPhone model and Face ID system.

3. Make Sure Your Face Is Visible

For standard Face ID, the TrueDepth camera should have a clear view of your eyes, nose, and mouth. Move anything blocking those features.

Possible obstructions include:

• A face mask when Face ID with a Mask is not configured
• A scarf or high collar
• Hair covering the eyes
• A helmet or protective equipment
• A hand resting over the face
• Sunglasses that block infrared light

Face ID works with many ordinary glasses and sunglasses, but some lenses can prevent the infrared system from seeing the eyes. Remove the glasses and test again.

Changes such as facial hair, makeup, and gradual aging are normally learned over time. A major difference in appearance can still require an alternate appearance or a new Face ID setup.

4. Hold the iPhone at the Correct Distance and Angle

Face the TrueDepth camera directly and hold the iPhone approximately 10 to 20 inches, or 25 to 50 centimeters, from your face. This is similar to the distance used for a selfie or FaceTime call.

Avoid holding the phone:

• Flat on a desk far below your face
• Extremely close to your eyes
• Too far away
• At a severe side angle
• With a finger covering the camera area

Raise the iPhone slightly and look toward the display. If Require Attention for Face ID is enabled, your eyes must be open and directed at the screen.

Face ID on iPhone 13 and later can work in portrait and landscape when using iOS 16 or later. Earlier iPhone models require portrait orientation. Face ID with a Mask does not work in landscape mode.

5. Check Face ID Settings

Face ID may unlock the iPhone but remain disabled for purchases, Apple Pay, password autofill, or apps.

1. Open Settings.
2. Tap Face ID & Passcode.
3. Enter the passcode.
4. Confirm that Face ID is set up.
5. Enable the appropriate option under Use Face ID For.

Options can include:

• iPhone Unlock
• iTunes & App Store
• Wallet & Apple Pay
• Password AutoFill
• Other Apps

The exact list varies by iOS version and region. If Face ID works in one place but not another, check the individual permission before resetting everything.

For a third-party app, tap Other Apps and confirm that access is enabled. The app may also have its own biometric-login switch.

6. Restart the iPhone

A restart refreshes iOS services and the TrueDepth camera connection.

Restart Through Settings

1. Open Settings > General.
2. Tap Shut Down.
3. Drag the slider.
4. Wait about 30 seconds.
5. Hold the Side button until the Apple logo appears.

Restart With the Buttons

1. Hold the Side button and either Volume button.
2. Drag the power-off slider.
3. Wait for the iPhone to switch off.
4. Hold the Side button to start it.

The passcode is required immediately after every restart. Enter it once, lock the screen, and then test Face ID.

If the phone is frozen, use the correct force restart iPhone sequence. A force restart does not erase personal data.

7. Update iOS

Apple recommends installing the latest compatible iOS version when Face ID is not working.

1. Back up important data.
2. Connect to Wi-Fi and power.
3. Open Settings > General > Software Update.
4. Download and install any available update.
5. Enter the passcode after restart.
6. Test Face ID again.

Updates can correct software and compatibility problems, but they cannot repair a cracked TrueDepth component or an incorrectly installed replacement part.

8. Set Up an Alternate Appearance

Face ID gradually adapts to changes, but an alternate appearance can help when you regularly look substantially different.

1. Open Settings > Face ID & Passcode.
2. Enter the passcode.
3. Tap Set Up an Alternate Appearance.
4. Position your face inside the frame.
5. Move your head slowly to complete both scans.

Use this for your own significantly different appearance, not to add several unrelated people. A person whose appearance is enrolled may be able to authenticate actions enabled for Face ID.

If Set Up an Alternate Appearance is unavailable, one may already be enrolled. Resetting Face ID removes both the main and alternate scans.

9. Reset and Set Up Face ID Again

Reset Face ID when recognition remains poor after cleaning, positioning, settings checks, restart, and update.

1. Open Settings > Face ID & Passcode.
2. Enter the passcode.
3. Tap Reset Face ID.
4. Restart the iPhone.
5. Return to Face ID & Passcode.
6. Tap Set Up Face ID.
7. Hold the iPhone in portrait orientation.
8. Position your face inside the frame.
9. Move your head slowly to complete the first scan.
10. Complete the second scan and tap Done.

Remove a mask and sunglasses during the standard setup. Use even lighting and make sure nothing covers the camera.

Resetting Face ID deletes the stored facial representation from the iPhone. It does not erase photos, messages, apps, or other personal data.

If setup cannot complete with a clear face and unobstructed camera, investigate hardware and repair history.

10. Turn Attention Settings Off Temporarily for Testing

By default, Face ID checks that your eyes are open and looking at the iPhone. This adds security and helps prevent someone from unlocking the phone without your attention.

To test whether attention detection is causing the failure:

1. Open Settings > Accessibility > Face ID & Attention.
2. Review Require Attention for Face ID.
3. Turn it off temporarily if appropriate.
4. Test Face ID.

Disabling attention makes Face ID less demanding but reduces protection. Re-enable it after testing unless an accessibility need makes the change necessary.

Attention settings do not fix a damaged TrueDepth camera. If Face ID setup fails completely, continue to the hardware checks.

11. Fix Face ID Not Working With a Mask

Face ID with a Mask is available on iPhone 12 and later with supported iOS versions. It recognizes distinctive features around the eyes rather than requiring the entire face.

Enable Face ID With a Mask

1. Open Settings > Face ID & Passcode.
2. Enter the passcode.
3. Turn on Face ID with a Mask.
4. Tap Use Face ID with a Mask when prompted.
5. Follow the onscreen enrollment instructions.

You do not need to wear a mask while completing this setup.

For it to work:

• The eyes and surrounding area must remain visible.
• A mask worn too high can block recognition.
• It does not work with sunglasses.
• It does not work in landscape orientation.
• The phone must be an iPhone 12 or later that supports the feature.

If you wear glasses, use Add Glasses in Face ID & Passcode settings. Apple allows multiple pairs of ordinary glasses to be added for mask recognition.

12. Fix Face ID Not Working With Sunglasses or Glasses

Clean the lenses and make sure the frames do not cover the eyes excessively. Test without glasses to identify whether they are responsible.

Most transparent prescription glasses and many sunglasses work. Some sunglasses block infrared light, preventing the TrueDepth camera from seeing the eyes.

Face ID with a Mask is not designed to work with sunglasses. Remove them when both the mask and sunglasses are being worn.

If Require Attention is enabled, certain dark or infrared-blocking lenses can also interfere with eye detection. Do not permanently weaken security settings until you have tested another pair of glasses.

13. Fix Face ID Not Working in Landscape Mode

Landscape Face ID requires:

• iPhone 13 or later
• iOS 16 or later
• Standard Face ID without Face ID with a Mask active for that attempt

Earlier Face ID iPhones require portrait orientation. Rotate the phone upright and face the camera.

On a supported model, clean the camera, remove obstructions, and update iOS. Make sure a hand is not covering the TrueDepth system while holding the phone sideways.

14. Fix Face ID Not Working for the App Store

If Face ID unlocks the iPhone but purchases still request the Apple Account password:

1. Open Settings > Face ID & Passcode.
2. Enable iTunes & App Store.
3. Confirm that the correct Apple Account is signed in.
4. Try a download or purchase.
5. Enter the Apple Account password when required for the first transaction.
6. Test Face ID on a later eligible prompt.

Apple can request the account password after a restart, security change, billing update, or unsuccessful authentication. That does not automatically indicate a TrueDepth failure.

Screen Time restrictions and managed-device policies can block purchases regardless of Face ID.

15. Fix Face ID Not Working With Apple Pay

Check that Face ID works for normal iPhone Unlock. Then verify:

1. Wallet & Apple Pay is enabled under Face ID & Passcode.
2. A valid payment card remains in Wallet.
3. The iPhone passcode is active.
4. The card issuer has not suspended the card.
5. Apple Pay is available in the region.

For in-store payment, double-click the Side button, authenticate with Face ID, and hold the iPhone near the reader. If recognition fails, enter the passcode when offered.

When Face ID succeeds but the payment is declined, contact the card issuer. That is a payment problem rather than biometric recognition failure.

16. Fix Face ID Not Working in One App

An app can disable biometric login independently of the iPhone Unlock setting.

Try these steps:

• Sign in with the app’s password or PIN.
• Open its security settings and enable Face ID.
• Go to Settings > Face ID & Passcode > Other Apps and allow the app.
• Update the app through the App Store.
• Close and reopen it.
• Restart the iPhone.
• Disable and re-enable Face ID inside the app.
• Reinstall only after confirming that data and credentials are backed up.

Banking, health, and password-management apps may intentionally require their full password after an update, account change, repeated failure, or restored backup.

17. Check the Front Camera

Open Camera and switch to the front-facing camera. Test photos, video, Portrait mode where supported, and a FaceTime preview.

Problems such as a black image, unusual blur, focus failure, shaking, or camera errors can support the possibility of a front-camera or connection fault. However, a normal selfie does not guarantee that Face ID hardware is healthy because the TrueDepth system contains additional infrared components.

If both Face ID and the front camera failed after impact or repair, stop resetting the software and arrange an inspection.

“Face ID Is Not Available” or “A Problem Was Detected With the TrueDepth Camera”

These messages can appear when iOS cannot use the TrueDepth system safely or correctly.

Try:

1. Restart the iPhone.
2. Update iOS.
3. Remove anything covering the camera.
4. Check Settings > General > About > Parts & Service History on supported models.
5. Consider recent damage or repair.

If the warning returns, use the passcode and arrange service. Apple states that a trained technician should handle a disabled Face ID system because improper work on its laser components can defeat safety mechanisms and risk harmful exposure.

Do not attempt to force-enable a disabled TrueDepth system with unofficial software, replacement flex cables, or hidden diagnostic codes.

Face ID Stopped Working After Screen Replacement

Display repair can affect Face ID when the TrueDepth components, cables, alignment, or calibration are damaged or incomplete.

Open Settings > General > About and look for Parts & Service History if the model supports it. Messages can indicate an unknown part or an unfinished repair.

For supported genuine front-camera repairs, the iPhone may display Finish Repair next to TrueDepth Camera. Apple says Face ID cannot be used until the calibration is completed with Repair Assistant.

To finish an eligible repair:

1. Update to the latest iOS version.
2. Open Settings > General > About.
3. Tap Parts & Service History.
4. Select Restart & Finish Repair.
5. Follow the Repair Assistant instructions.

Availability depends on the iPhone model, part, country, repair method, and software. Return to the service provider when the option is missing or completion fails.

Face ID Stopped Working After a Drop or Liquid Exposure

A drop can damage the camera array, display, internal connectors, or frame alignment even when the front glass is intact. Liquid can cause corrosion that develops gradually.

Warning signs include:

• Face ID failed immediately after impact
• The display lifted or cracked near the sensor area
• The front camera also behaves abnormally
• The TrueDepth warning appears
• The phone restarts unexpectedly
• Moisture is visible inside a camera lens

Back up the iPhone and arrange inspection. Do not charge a wet device, use a hair dryer, insert tools, place it in rice, or press on a separated display.

Face ID Works Only Sometimes

Intermittent Face ID usually improves when you make recognition conditions consistent:

• Clean the camera area regularly.
• Hold the phone within the recommended distance.
• Look toward the screen.
• Remove infrared-blocking sunglasses.
• Keep eyes, nose, and mouth visible.
• Set up Face ID with a Mask correctly when needed.
• Add an alternate appearance for a substantial recurring change.
• Reset Face ID and enroll again in good lighting.
• Update iOS.

Face ID uses infrared and can work in darkness, so ordinary low light alone should not stop it. The phone still needs a clear view and correct distance.

If reliability declines after physical damage or repair, treat it as a possible hardware problem.

Face ID Unlocks the Phone but Does Not Open the Home Screen

Face ID unlocks the device, but it does not automatically dismiss the Lock Screen in the normal configuration. After the padlock opens, swipe up from the bottom of the screen to reach the Home Screen.

This is expected behavior. The iPhone displays notifications and other Lock Screen information after successful recognition until you swipe.

If the swipe does not respond, investigate an iPhone touchscreen not working problem rather than resetting Face ID.

Can AssistiveTouch Replace Face ID?

AssistiveTouch can replace physical button presses and gestures, but it cannot scan a face or provide biometric identity.

It can help you:

• Lock the screen
• Open App Switcher
• Restart the iPhone
• Take a screenshot
• Activate Siri
• Use gestures

Use the passcode when Face ID is unavailable. Do not share the passcode with a repair provider unless it is necessary and you understand why it is being requested.

Reset All Settings

Reset All Settings is a later software step when Face ID can still be configured but behaves incorrectly across iOS.

1. Back up the iPhone.
2. Open Settings > General > Transfer or Reset iPhone.
3. Tap Reset.
4. Select Reset All Settings.
5. Enter the passcode and confirm.

This does not delete personal files, but it resets Wi-Fi networks, privacy settings, keyboard choices, location preferences, and Apple Pay cards.

Do not erase the iPhone as an early fix. A factory reset cannot repair damaged TrueDepth hardware, and Face ID must be set up again afterward.

When Face ID Needs Professional Service

Arrange service when:

• Face ID setup cannot be completed
• iOS says Face ID is unavailable or disabled
• A TrueDepth camera problem is detected
• The front camera or Face ID failed after a drop
• The issue began after display or camera repair
• The camera area is cracked or physically damaged
• The iPhone had liquid exposure
• Repair Assistant cannot finish calibration
• Supported software fixes make no difference

Apple advises that TrueDepth and its laser systems should be serviced by a trained technician using appropriate parts and procedures. Back up the iPhone before service and ask the provider whether biometric authentication will remain functional after the proposed repair.

Frequently Asked Questions

Why did Face ID suddenly stop working?

A dirty or covered TrueDepth camera, blocked face, wrong angle, required passcode, temporary iOS problem, or disabled setting may be responsible. Sudden failure after impact, liquid, or repair suggests hardware.

How do I reset Face ID?

Open Settings > Face ID & Passcode, enter the passcode, and tap Reset Face ID. Then select Set Up Face ID and complete both facial scans.

Why does Face ID keep asking for my passcode?

iOS deliberately requires the passcode after a restart, repeated failed scans, and certain security events. Enter it once and test Face ID during a normal unlock.

Does Face ID work in the dark?

Yes. The TrueDepth system uses infrared technology and does not depend only on visible light. The camera still needs a clear view at an appropriate distance.

Can Face ID work with a mask?

Face ID with a Mask is supported on iPhone 12 and later with compatible iOS. Enable it under Face ID & Passcode. The eyes must remain visible, and the feature does not work with sunglasses or in landscape mode.

Why does Face ID work for unlocking but not the App Store?

The iTunes & App Store option may be disabled, or Apple may require the Apple Account password for the first purchase or a security check.

Can a screen protector stop Face ID?

Yes, if it covers, distorts, or traps debris over the TrueDepth camera. Remove it and test, then use one made for the exact iPhone model.

Can Face ID be repaired after a screen replacement?

It depends on which component was affected and whether the TrueDepth system is intact and properly calibrated. Supported repairs may require genuine parts and Repair Assistant. A trained provider should diagnose it.

Will a factory reset fix Face ID?

It may resolve a rare software problem but cannot repair damaged camera hardware or an unfinished calibration. Try the supported checks and Reset Face ID before considering an erase.

Is Face ID safe for the eyes?

Apple designs the TrueDepth system with safety mechanisms. If Face ID is disabled because a problem is detected, do not attempt an unqualified repair. Apple warns that improper repair or nongenuine components in its laser systems can defeat safety protections.

The safest sequence is to clean the TrueDepth area, remove obstructing accessories, make the full face visible, use the correct distance and orientation, verify settings, restart, update iOS, and reset Face ID. When setup still cannot finish or the problem follows physical damage or repair, use the passcode and arrange qualified service rather than trying to bypass a disabled biometric system.
