Whether your Touch ID has stopped working altogether or is simply being finicky, this post is for you. By the end, you’ll have the knowledge and tools you need to troubleshoot Touch ID issues like a pro. Let’s get started!

Possible Causes of Touch ID Issues

Some users might find themselves unable to activate Touch ID, or experiencing issues with the feature not working as expected. Here are some possible causes that could explain why Touch ID is not functioning properly:

Dirty or Wet Fingers/Home Button

One of the most common reasons why Touch ID fails is because the Home button and/or user’s fingers are dirty, wet, or oily. Touch ID requires a clear, dry fingerprint to recognize and authenticate the user. Dirt and oil can obscure the fingerprint, causing recognition issues.It’s worth checking if there’s any visible dirt or moisture present on the Home button or your fingers. If so, wipe them off with a soft, dry cloth and try using Touch ID again. Make sure your fingers are also dry before attempting to use Touch ID.

Touch ID & Passcode Settings

Another reason why Touch ID might not be working is that Touch ID & Passcode settings may not be configured properly. In Settings, navigate to Touch ID & Passcode, and ensure that the iPhone Unlock or iTunes & App Store option is turned on. If it’s off, toggle it on and confirm it’s set up correctly.

Software Glitch

Sometimes, a software glitch can cause Touch ID to malfunction. This is usually due to bugs in the iOS operating system. If the above steps did not work, try force restarting your iPhone by holding down the power and home buttons at the same time until the Apple logo appears. Then try using Touch ID again.If a software glitch is still causing issues, try resetting all settings by going to Settings > General > Reset > Reset All Settings. This won’t delete your data, but it will erase all custom settings, so consider this option carefully.If neither of these solutions work, a software update through iTunes or a third-party tool like Reiboot could help, but they require some technical know-how. Refrain from doing this step if you are not familiar with these tools.

Faulty Hardware

Sometimes, Touch ID issues could be caused by faulty hardware. If your iPhone is still under warranty, schedule an appointment with the Apple Store and they should be able to diagnose the issue and fix it for you. If it’s out of warranty, it might be worth consulting a third-party repair shop.


Having issues with Touch ID can be frustrating, but following the troubleshooting tips mentioned should help you get it working again. If you’ve exhausted all of the options and Touch ID is still not working, it could be time to take your iPhone to a specialist to diagnose what’s going wrong.

Solutions to Fix Touch ID Issues

If you’re encountering problems with your iPhone’s Touch ID, don’t worry, there are solutions available. Here are some troubleshooting tips that you can try.

1. Ensure Your Fingers and Home Button are Clean and Dry

The first and foremost thing to do is to ensure that your fingers, as well as the Home button, are clean and dry. If there is moisture, dirt, or sweat on your finger or the button, then Touch ID may not work accurately. Use a soft cloth to clean both the finger and the Home button to remove any smudges, and then try using Touch ID again.

2. Make Sure iPhone Unlock or iTunes & App Store is On

Sometimes, Touch ID won’t work if the settings for iPhone Unlock or iTunes & App Store are turned off. To turn them on, go to the “Touch ID & Passcode” section of the “Settings” app and check if the toggle buttons for these options are on. If not, turn them on, and then try using Touch ID to see if it works.

3. Force Restart the Phone

If none of the above methods works, it’s time to try restarting the iPhone. To force restart an iPhone, press and hold the “Sleep/Wake” and “Home” buttons simultaneously until the Apple logo appears on the screen. Then try using Touch ID to see if it works.

4. Reset All Settings

If the above steps haven’t worked, try resetting all settings to their default state. This will erase any saved preferences, but it does not erase any data or media. To reset all settings, go to “Settings,” then “General,” then “Reset.” From there, click “Reset All Settings” and enter your passcode. Once reset, try using Touch ID to see if it works.

5. Update or Reinstall iOS Using iTunes

If none of the above steps have worked, try updating or reinstalling iOS using iTunes. Connect your iPhone to your computer, open iTunes, and select “Update” or “Restore iPhone”. You may need to enter your passcode or choose “Trust This Computer” on the device to proceed. If you choose to restore, it will erase all data from your device, so make sure to have a backup. Once complete, try using Touch ID to see if it works.

6. Repair iOS with Reiboot

Another option to try is to repair iOS using Reiboot. This is an iOS repair tool that helps fix various system problems, including Touch ID issues. Download and install Reiboot on your computer, connect your iPhone to your computer, and then select the “Repair Operating System” option. Follow the instructions provided by the software to fix the issue.

7. Delete and Add a New Fingerprint

If you’ve tried all of the above solutions and none of them have worked, the next step is to delete the existing fingerprint(s) and add a new one. Go to the “Touch ID & Passcode” section in “Settings.” Select the fingerprint that’s causing trouble, and then tap “Delete Fingerprint.” Once the fingerprint is erased, add a new one by following the on-screen instructions. This should fix the issue with Touch ID.In conclusion, if you’re encountering problems with Touch ID, it’s necessary to perform these troubleshooting steps to fix the issue.
