Touch ID Not Working on iPhone, iPad? Here Is How To Fix

This article explains what to do when Touch ID is not working.

Touch ID, Apple’s fingerprint recognition sensor, can be used with an iPhone 5s or later (e.g., iPhone 6 or iPhone 7), iPad Pro, iPad Air 2, or iPad mini 3 or later. Touch ID can be used for (a) unlocking your iOS device (b) making purchases (c) making Apple Pay purchases. Touch ID is an incredibly convenient feature and a lot more secure type of authentication.

Are your having issues with Touch ID? Did Touch ID stop working? For instance, some of our readers stated that Touch ID sometimes fails to work in the App Store. Sometimes you may experience problems after an iOS update. Or Is it not working as expected at all?

Please note that you may have to enter your passcode, Touch ID will not work, this is by design, for instance, if your device is turned off (e.g., your device will shut down by itself just before the battery is completely depleted), you will be asked to enter your passcode when you restart as your device will say “Touch ID requires your passcode when iPhone (or iPad) restarts”. Apple does not offer the ability to use Touch ID when the phone or iPad restarts.
