Setting up the fingerprint sensor on the Samsung Galaxy S23 is such an important security measure that it actually prompts you to do it when setting up your new phone. And it makes sense why Samsung is so keen that you take advantage of the Galaxy S23’s biometric capabilities. If your fingerprint is stored on your Galaxy S23, you can use the under-display sensor to unlock your phone. A fingerprint can also authenticate purchases you make on your smartphone.
If you skipped setting up the fingerprint sensor when you first got your Galaxy S23, don’t worry. It’s easy to come back later and set up the fingerprint sensor. You can also add up to four fingerprints to give yourself more flexibility when unlocking your Galaxy S23.
In this guide, we’ll walk you through setting up the fingerprint sensor on the Galaxy S23 so you can keep the personal information stored on your phone safe.
How to set up the fingerprint sensor on the Galaxy S23
Note: We used a Samsung Galaxy S23 for this tutorial on how to set up the fingerprint sensor on Samsung’s new flagships, but the same process will work if you have one Galaxy S23 plus or Galaxy S23 Ultra.
Before proceeding, if you plan to use a Galaxy S23 screen protector, make sure that it is compatible with your phone’s screen reader. If you set up your fingerprint before applying the screen protector, you may need to enroll that finger again.

If this is your first time enrolling a fingerprint on the Galaxy S23 and you haven’t yet set up a secure lock screen, the Galaxy S23 will prompt you to do so. Choose PIN, Password or Pattern as a backup method to unlock your phone.
I chose PIN for this guide. Follow the instructions on the screen And Enter your chosen PIN twice to confirm. From there you can proceed to set up the fingerprint sensor.
4. Register your fingerprint.

If you later decide to remove a fingerprint, Proceed to the Biometrics screen in step 2 and Tap Fingerprints. Select the fingerprint you want to remove with a tap and then select Remove in the upper right corner. You can also edit the name of the saved fingerprint on this screen.
And that’s all there is to it. More Galaxy S23 tips, e.g. How to take a screenshot on the Galaxy S23, for example, see our Samsung Galaxy Hidden Features guide. We also looked at hidden Android features that also apply to the Galaxy S23 phones.
