7 Ways You Can Solve 'Unable To Complete Touch ID Setup' Issue

Touch ID basically utilizes fingerprint identity sensor technology to provide a quick, secure, and convenient way of unlocking your iPhone and apps. However, sometimes you may face some errors when setting up Touch ID on your iPhone. You often end up with the message, “Unable to complete Touch ID setup” followed by the request to go back and try again. If you were trying to set up your Touch ID and encountered this error too, don’t panic!

We understand that it can be frustrating because the error means you can’t use Touch ID. Quite often, the culprit is a dirty fingerprint sensor or a system glitch. These are mostly the root causes. Fortunately, though, this is a common error that many have resolved easily. So, follow any of the solutions we’ve enlisted in this article and you’ll have your Touch ID set up in no time. Let’s get into them!

Clean Up the Touch ID Sensor and the Phone Case

As we mentioned earlier, one root cause of this unable to complete Touch ID setup error is a dirty/smeary fingerprint sensor and this often happens when you try to set up Touch ID after you’ve been using your iPhone for some time. Probably you were doing the initial setup or wanted to add maybe one or more fingerprints. To resolve this error then, you should clean the sensor and keep your finger, the phone’s Home button, and the screen, clean, clear, and dry.

  • Find a clean lint-free cloth (like a microfiber one) or tissue as they are ideal for removing grease and grime.
  • With the cloth, gently scrub/wipe your phone’s home button (which holds the Touch ID sensor). Use the cloth to also wipe your finger because the Touch ID might not work if your finger is wet.
  • When done, try to scan your finger once more.

You may also consider cleaning your phone’s case if it’s using one. If you still have issues with the Touch ID setup, then we recommend removing the case altogether and even the screen protector if you’ve put one on your iPhone. This will ensure nothing covers the Home button or interferes with the Touch ID setup process.

Change the Touch ID Settings

If the iPhone Touch ID settings are not properly adjusted, this could likely lead to the unable to complete the Touch ID setup issue you’re facing. Therefore, you need to ensure the settings are adjusted appropriately. To do that;

  • Open Settings, then tap Touch ID & Passcode. Put your passcode when prompted in order to move to the next step.
  • Now disable iPhone Unlock as well as iTunes & App Store.
  • Restart your iPhone.
  • Once it’s turned on, head to Settings again and tap Touch ID & Passcode. Put your passcode once more to proceed.
  • Enable iPhone Unlock as well as iTunes & App Store again.
  • Finally, retry setting up the Touch ID. Your iPhone should now complete the Touch ID setup.

Enroll a Different Finger

The fingerprint of the finger you’re seeking to register may have several issues and that’s why you can’t set up the Touch ID. For instance, if you’ve been a banker for a long time, constantly counting money could leave your thumb somewhat scarred permanently. Hence, you can’t set up Touch ID with such a thumb. Even if you have had a small cut on the fingerprint of your finger, or if it’s worn out due to repetitive tasks, you won’t be able to set up Touch ID.

So, if this your case, the best way you can remedy this problem is to add or use a different finger to set up the Touch ID function.

Force Restart the iPhone

Many technical iPhone issues can be resolved by performing a hard reboot. With that in mind, then it would be a good idea now to force restart your iPhone. It’s a quick, simple method compared to the others and it normally restores your entire device to its default state or full potential which is likely to unblock the Touch ID without resulting in any data loss.

Note though that while this method may fix the error, it only has a success rate of 50%. Follow these steps to hard boot your iPhone.

  • For iPhone 6, long-press the Home and Sleep/Wake buttons concurrently. Release them once you see the Apple Logo.
  • For iPhone 7/7 Plus, follow the same method as above but this round long-press the Volume Down and Sleep/Wake buttons instead.
  • For iPhone 8 or newer versions (such as iPhone X/11/12), the process is a bit complicated. Quickly, press the Volume Up button, then release it. Next, long-press the Volume Down and Sleep/Wake buttons concurrently until you see the Apple logo.
