Touch ID is one of the most secure ways to protect your iPhone and your privacy. It is critical for iPhone users who own models before the iPhone X, such as the popular iPhone 5S/6/6S/6S Plus/7/8. Activating your iPhone's Touch ID is easy. However, there is a chance that you may have trouble starting it, including receiving the "Unable to activate Touch ID on This iPhone" error message.

In this article, we will show you how to resolve this issue. If you can't unlock your iOS device with Touch ID, can't enroll a fingerprint, or are prompted to enter your passcode, this is where you'll find it helpful. These methods are compatible with every Apple device model.

Part 1. Why Has Touch ID stopped Working on My iPhone?

Because Touch ID is dependent on both software (e.g., iOS) and hardware (sensors) to function properly, failures can occur from a variety of sources, including:

  • Dirty Home Screen: Touch ID activation requires a clean and dry home button, and a dirty one may cause the touch sensor to fail.
  • Phone Unlock or iTunes & App Store is turned off: Touch ID can only be normally activated when Phone Unlock or iTunes & App Store is turned on.
  • iOS-related issue: Incompatibility with the latest iOS version, glitches during the download and installation of the newest iOS and older iOS versions.
  • When you first set up Touch ID, you scanned your fingerprint incorrectly.
  • The sensor - or your finger - is dirty.
  • Your iOS version is out of date.
  • You're moving your finger or pressing too hard on the sensor (or too softly).
  • The scanner is being obstructed by a case or screen protector.

Part 3. What Do You Usually Do if You Can't Activate Touch ID? [Common Ways from Apple Support]

iPhone system issues such as "Touch ID cannot be activated on this iPhone" or "Unable to activate Touch ID on this iPhone" may significantly impair and affect user experience. Although they are rarely encountered problems, many people have encountered them. Here are the troubleshooting options you can try to fix the Touch ID activation issue for good.

Option 1: Force Restart Your iPhone

Although software bugs are extremely rare on iPhones, they do occur from time to time. In that case, a simple force restart should solve the problem once and for all. To force restart your iPhone, press and quickly release the Volume up button, then the Volume down button, and finally the Side button. When you see the Apple logo, let go of the button.

Option 2: Make Sure Your Finger and Home Button are Clean

In most cases, if you try to use the Touch ID feature with a dirty or wet finger, the iPhone cannot read your fingerprint, and it simply displays the "Unable to activate Touch ID on this iPhone" error message.

You can avoid such problems by cleaning and drying the home button and your finger. To clean the home button, gently wipe it with a lint-free cloth.

Option 3: Try Enrolling With a Different Finger

If the specific finger cannot be identified, create a new fingerprint with a different finger. Close the iPhone and try to unlock it using the newly-set fingerprint. When we get a cut on our fingers or something similar, it makes it difficult for the sensors to identify our fingerprints. At such times, trying out a new fingerprint is often successful.
