Delete Unknown Fingerprints from Your iPad (or iPhone)

* This article is from our Tip of the Day newsletter. . *

A good way to maintain a secure device is to ensure no one can access it but you. Having a passcode that you keep to yourself is a great way to keep a device private, but a device that uses Touch ID may end up with a few extra fingerprints from unknown persons. But you might not have known that you can actually test which fingerprints are yours and which fingers they belong to! Here's how to determine unknown fingerprints and delete them.

Why You'll Love This Tip:

  • Figure out which fingerprints are yours and which fingers they belong to.
  • Delete unknown or extra fingerprints from your device to keep it secure.

How to Delete Unknown Fingerprints

System Requirements

An Apple device with Touch ID capabilities is required to perform this tip. Devices with Touch ID include the iPhone 7, 7+, 8, 8+, SE (2nd & 3rd gen), and iPad Pro (2nd gen or later), iPad Air (3rd gen or later), and the iPad Mini (5th gen or later). This tip was performed on a 5th-generation iPad Air running iPadOS 17.3. Learn how to update to the latest iOS.

After checking which fingerprints are yours and which fingers they belong to, I suggest editing the name on each fingerprint as you save it. This will ensure that no one has added fingerprints to your Touch ID and keep track of the fingerprints you have added.
