How to Register Your Fingerprint on a Galaxy Tab S2 NOOK

By Corey Sandler

The electronic fingerprint reader in the Home key of your Galaxy Tab S2 NOOK can identify certain unique — or at least rare — characteristics of the markings on the end of one of your fingers. It’s not a perfect system, but you can experiment with friends and family, especially siblings. Here’s your chance to blame everything on your brother or sister if their fingerprints prove similar enough to fool the reading device.

You can register as many as four fingerprints, and a password will also be recorded as an alternative means of entry to the tablet.

  1. From the Home screen, tap the Apps icon and then the Settings (gear) icon.

  2. Tap Lock Screen and Security, and then tap Fingerprints.

  3. Choose an option:

    • To add a fingerprint, tap Add Fingerprint and follow the instructions. You have to apply and reapply your finger about ten times so that the system has a number of samples.

    • To rename a fingerprint, touch and hold the fingerprint and then tap Rename.

    • To delete a fingerprint, touch and hold the fingerprint on the screen and then tap Remove.

To change the backup password for your fingerprints, do this:

  1. From the Home screen, tap the Apps icon, and then tap the Settings (gear) icon.

  2. Tap Lock screen and Security, and then tap Fingerprints.

  3. Tap Change Backup Password.

  4. Enter a new password.

Fingerprints can also give you access to your Samsung account and certain online accounts. You’ll find an option for those settings in the same Lock Screen and Security section.
