How to Fix Face ID and Touch ID on iPad

Resolve authentication failures on iPad by resetting biometric sensors, clearing cache, and managing iPadOS security settings for Face ID and Touch ID.

1. Clean the sensor area. Debris, oil, or screen protector residue can obstruct the TrueDepth camera or the Touch ID sensor. Use a clean, dry microfiber cloth to wipe the top bezel of your iPad. Ensure no smudges remain over the camera array or the home button sensor.
2. Check for software updates. Outdated firmware often causes biometric sensor instability. Navigate to Settings > General > Software Update to check for pending iPadOS versions. Install any available updates to ensure your security drivers are current.
3. Remove obstruction or accessories. Confirm that your case or screen protector does not cover the camera notch or the Touch ID button. If an accessory overlaps the sensor array, remove it to test if functionality returns. If the sensor works without the accessory, the hardware is not at fault.
4. Delete and re-enroll biometrics. Corrupt biometric data requires a fresh scan. Go to Settings > Face ID & Passcode or Touch ID & Passcode, enter your passcode, and delete existing appearances or fingerprints. Tap 'Set Up Face ID' or 'Add a Fingerprint' and follow the on-screen prompts to register your data again.
5. Perform a force restart. A force restart clears temporary system glitches affecting hardware services. For models without a Home button, press and quickly release the Volume Up button, press and quickly release the Volume Down button, then press and hold the Power button until the Apple logo appears.
