Touch ID – Add, delete and set up new fingerprints

Touch ID is the name given by Apple for securing the devices offered using a fingerprint. In addition to some iPhone models, iPad and Mac models can also be secured by fingerprint. Scanning a fingertip quickly replaces entering a password or PIN, but this can also become a problem. Because multiple fingerprints can be saved for Touch ID on iPhone, iPad and Mac. To find out whether only your own are stored, and to reset Touch ID, there are the options described below.

With Touch ID you can secure and quickly unlock your iPhone, iPad and Mac with your fingerprint. Manage Touch ID fingerprints on iOS, iPadOS and macOS as described in this guide.

Check Touch ID fingerprints on iPhone and iPad

To set up the Touch ID on the Apple smartphone or Apple tablet, to manage the stored fingerprints and, if necessary, to set up the backup again, the way leads through the settings. On iOS and iPadOS, you can find this on one of the Home screens or in the App Library under the name "Settings":

  • Opens the Settings your mobile Apple device
  • Select the menu item Touch ID & Code from
  • Enter the unlock code to verify that you can make changes here
  • Now you can identify individual entries by scanning on the home button
  • You can also delete Touch ID entries, reset the whole thing and more

Manage and reset Touch ID on Mac

Whether via an appropriately equipped Apple keyboard or the fingerprint sensor in the MacBook - Touch ID can also be used under macOS to identify yourself as a legitimate user and to verify certain processes. To check whether only the users who are actually supposed to have access have access, you can also go to the “System settings” here:

  • Opens the  menu in the menu bar System settings ...
  • Click on in the overview that now appears touch ID
  • If prompted, enter your account password
  • Now set up a fingerprint, delete a stored one or simply check the previously saved ones
  • If you don't recognize one of the entries, you can delete it to make the Mac more secure
