Touch ID is very useful for authenticating purchases within apps using your fingerprint rather than entering your account password. This is a more secure form of authentication and also makes the process much faster.
Unfortunately, not everything is perfect. Sometimes Touch ID fails to work properly in the App Store for authenticating purchases. Instead of displaying a prompt to use your fingerprint for authentication, the App Store may ask you to enter your account password instead.
If you’re facing a similar issue, no need to worry as we will show you how to fix this problem in the guide below.
Fix Touch ID Not Working in the App Store
Step 1: On your iPhone or iPad, launch the Settings app and navigate to Touch ID & Passcode section. You might be asked to enter your passcode, if enabled.
Step 2: Turn off the toggle for iTunes & App Store.
Step 3: Next, reboot your device. Hold down the lock/sleep button to switch it off. Repeat the same process to turn it on.
Step 4: Go back to the Touch ID & Passcode section in Settings.
Step 5: Turn on the toggle for iTunes & App Store.
After following the above steps, if you attempt to purchase anything from the App Store, you should be asked to use Touch ID rather than entering your Apple ID password. Keep in mind that App Store requires you to enter your Apple ID password if you haven’t purchased anything within the last 24 hours.
Sometimes the issue can be caused due to a hardware problem with Touch ID. So make sure that Touch ID is working as intended. You can verify this by using Touch ID on the Lock screen to see if it unlocks your device.
