Touch ID is a useful and secure feature for Apple users, but issues can arise. If your iDevice’s Touch ID suddenly refuses to recognize your fingerprints, follow these troubleshooting steps to fix the problem.
If Touch ID doesn’t work from the first moment you take your iPhone or iPad out of the box, you may want to book a Genius appointment at the Apple Store to have them check it. The part may be faulty and you may need a replacement.
Clean the Scanner
The first step in repairing an unresponsive fingerprint scanner is cleaning the Touch ID sensor. This sensor uses a high-resolution image of the sub-epidermal layers of your skin to read your fingerprint, so if there is dust or grime on the Home button, your iPhone or iPad may find it difficult to confirm your identity. Use a lint-free cloth to clean the Home button.
Update iOS or macOS
Make sure your iPhone or iPad’s operating system is up to date by going to Settings > General > Software Update. Updating the software may fix the Touch ID issue, as Apple often uses minor iOS updates to fix bugs and make improvements.
Place Your Finger Accurately
Ensure you fully cover the Home button when using the fingerprint sensor, and be careful not to tap or press too hard. Keep your finger still while scanning to ensure accuracy.
Check Your Case
Check if your iPhone or iPad case has a cutout that is too tight, obstructing part of your fingerprint. You may need to find another case that allows for better fingerprint recognition.
Enable Touch ID Unlocking
Enable iPhone Unlock by going to Settings > Touch ID & Passcode > Touch ID, and ensuring the option is enabled. You can also enable iTunes & App Store if you want to use your fingerprint to make purchases.
Add More Fingerprints
You can add up to five fingerprints to your device for flexibility. Go to Settings > Touch ID & Passcode > Touch ID to add more fingerprints.
Add Fingerprints in Cold Weather
Cold weather can cause your fingerprints to change, potentially confusing the fingerprint scanner. If you’re experiencing Touch ID issues in the cold, try registering new fingerprints while your fingers are cold.
Register a Fingerprint Again
If a registered fingerprint isn’t working, you can re-register it in Settings > Touch ID & Passcode > Touch ID > Edit.
Clean Your Fingers
Moisture, lotions, sweat, oils, cuts, or dry skin on your fingers can also affect fingerprint recognition. Keep your fingers clean and dry for optimal Touch ID performance. If none of these troubleshooting steps work, make an appointment with an Apple Genius.
FAQs
Can I use Touch ID after replacing the Home button?
If you replace the Home button on your iPhone or iPad, the Touch ID sensor will no longer work. Only Apple can replace the Home button and restore the Touch ID sensor function.
How accurate is Touch ID?
Touch ID has a high level of accuracy, with a false positive rate of 1 in 50,000. However, fingerprints can change over time due to various factors, so it’s important to keep your fingerprints up to date on your device.
