But, if you still own an older generation of iPhone, it’s quite obvious that you use the touch ID hundreds of times in a day for different purposes.

But, what if your iPhone/iPad’s Touch ID stops working all of a sudden? Since you massively rely on it for daily authentication, it’s safe to say that “iPhone touch ID not working” can be a frustrating issue. Fortunately, there are a few solutions that can help you fix the problem.

If your iPhone’s Touch ID has also stopped working, continue reading; this guide will help you troubleshoot the problem by yourself. If one method is not working, try others instead.

1.1 Clean Touch ID or Check If It’s Not Wet

First and foremost, check your iDevice’s Touch ID. With daily use, it’s quite normal for the fingerprint scanner to accumulate dust, which can restrict it from properly reading the fingerprint. So, before everything else, take a lint-free cloth and make sure to precisely wipe-off any dust particles from the scanner.

Secondly, make sure that your fingers are clean as well. Usually, when your hands are wet or sweaty, the fingerprint scanner on an iPhone/iPad won’t read the fingerprint at all. So, if you’ve come out of the shower or trying to unlock the device after a workout, first clean your hand properly and then use the Touch ID.

1.2 Scan Fingerprint Accurately

Another reason that might cause the “Touch ID not working iPhone 8” problem is the wrong placement of your finger on the scanner. Ideally, the scanner is capable of reading the fingerprint with a light touch. However, there are many users who either try to press too hard on the home button or don’t place their thumb/finger properly. To make sure that your finger placement is accurate, simply ensure that your whole finger covers the scanner.

1.3 Remove iPhone Case/Cover

No doubt cases and covers are perfect to protect your iPhone from accidental damage, but they can also interfere with several functions of the device itself. If your case/cover is partially covering the Touch ID scanner, it would be better to remove it and install a new cover with a better fit.

Fix 2: Disable and Enable Touch ID

After cleaning the Touch ID, if it still fails to read your fingerprint, it’s quite possible that the problem is being triggered by an internal software-bug. In this situation, simply disable the Touch ID for a while and re-enable it again.

To do this, go to “Settings” > “Touch ID & Passcode” and enter your screen passcode to authenticate yourself. Then, toggle every switch off to disable Touch ID completely. Finally, wait for a few minutes and repeat the same process to turn on the Touch ID again.

Fix 3: Restart iPhone

Like many other iOS errors, you can also fix the iPhone Touch ID not working by simply rebooting your device. However, if a regular restart doesn’t work, you can also perform a hard reset to fix the Touch ID.

To perform a hard reset, press and hold both the Volume Down and Side buttons simultaneously for at least 10 seconds. Release the buttons as soon as the Apple logo appears on your screen. Your iPhone will restart automatically and you’ll notice that the Touch ID won’t face the same problem anymore.

Fix 4: Delete and Re-Add Fingerprint

While it’s not an official method, many online forums claim that one can fix the Touch ID problems by deleting all the fingerprints from their device and re-adding them later on. So, if none of the above solutions work, you can also try this method to fix the problem. Follow these steps to delete and re-add fingerprints on an iDevice.

Step 1 - Go to “Settings” and click “Touch ID and Passcode”. Then, enter your passcode to proceed further.
