Touch ID Not Working? How to Fix TouchID!
Is your Touch ID sensor broken? Or simply not responding for software reasons? This is a guide on how to fix a case of Touch ID not working on your iPhone or iPad. The Touch ID fingerprint sensor is a marvel in terms of ease-of-use, never has it been so easy to safely authenticate with your finger instead of using a long and complex password. Sometimes, your iPhone’s Touch ID sensor will give you a hard time. This is what you can do about it.
Setting up Touch ID
The iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air 2 and iPad Mini 3 have support for Touch ID and include the hardware sensor, which is embedded in the Home Button. Older devices will not display the settings for the sensor, as it is not present in the respective Home Button of earlier models. To set up Touch ID, go to “Settings” and “Touch ID & Passcode”.
Touch ID not working: What to check first
Resolving issues with the Touch ID sensor on your iPhone or iPad often involves rejected fingerprints. Try wiping the sensor with a lint-free piece of cloth and make sure that your fingers and the button are both clean and dry. Don’t press too firmly and keep your finger motionless while the sensor is scanning. Make sure to cover the sensor completely using your fingertip.
If there is no reaction at all, try checking the “Settings” app in the “Touch ID & Passcode” section and verify that you actually have “iPhone Unlock” and “iTunes & App Store” enabled in the Touch ID settings. Also verify whether your fingerprint is enrolled by tapping the “Finger” sections.
If everything checks out, you may try re-enrolling another finger. If that is not possible or you receive an error message while doing so, you have probably encountered a hardware defect and will have to go to an authorized Apple Service Provider.
