Tips for Optimizing Your Fingerprint Security
Now that you know how to change your fingerprint on the Samsung S21, here are some tips to optimize the success and security of your fingerprint recognition:
1. Clean Your Finger and Screen Regularly
Because the fingerprint scanner uses an ultrasonic approach, it’s sensitive to dirt, oil, and moisture. Make sure to clean your screen and your fingers before registering a fingerprint for optimal performance.
2. Use Multiple Fingerprints
Adding multiple fingerprints can improve accessibility. You might consider registering different fingers—like a thumb and an index finger—so you can unlock your phone from various angles and situations.
3. Update Your Software Regularly
Keeping your Samsung S21 updated with the latest software ensures you have the most secure and effective features available, including fingerprint recognition updates. Check for software updates in the “Software Update” section in your settings.
Maximizing Fingerprint Performance
While you may have successfully added and changed fingerprints, performance can vary. Below are additional recommendations on how to maximize the efficiency of your fingerprint sensor:
1. Adjust the Sensitivity Settings
Sometimes, the default settings may not work optimally for every user. Go to the “Advanced” settings in the fingerprint menu to adjust the sensitivity if available.
2. Re-register Fingerprints if Recognition is Poor
If you’re finding that your fingerprint is not recognized as easily, consider removing and re-registering your fingerprints. This ensures you are capturing the best representation of your finger.

To do this, follow the steps to access the fingerprint settings as mentioned earlier. Once there, you can see a list of your existing fingerprints, from which you can select and delete any that you no longer wish to use.
Additionally, ensure that your fingers are clean and dry before registering a new fingerprint. This will help the sensor accurately capture your fingerprint and improve the recognition accuracy. It’s also beneficial to choose a fingerprint that is generally not used frequently, as this can enhance security.
Can I register multiple fingerprints on my Samsung S21?
Yes, the Samsung S21 allows you to register multiple fingerprints. This feature is useful for accommodating different fingers or even allowing trusted individuals to access your device if necessary. You can add up to four different fingerprints on your device, ensuring that you have backup options in case one finger isn’t recognized for any reason.
To add additional fingerprints, go to the fingerprint settings and simply select the “Add fingerprint” option. Follow the on-screen prompts to scan the chosen finger until the registration is complete. Make sure to follow the proper scanning method for the best results.
How do I delete a previously registered fingerprint on Samsung S21?
To delete a previously registered fingerprint, begin by navigating to the fingerprint settings on your Samsung S21. Open the “Settings” app, go to “Biometrics and Security,” and select “Fingerprints.” After entering your PIN, pattern, or password, you will see all the fingerprints you have registered.
Choose the fingerprint you wish to delete and tap on it. You will then be presented with an option to remove the selected fingerprint. Confirm your choice, and that fingerprint will be erased from your device, allowing you to add or modify your registered fingerprints as needed.
Why is my fingerprint not being recognized on the Samsung S21?
If your fingerprint is not being recognized on your Samsung S21, there could be several reasons. Firstly, make sure that the fingerprint sensor is clean from dust and moisture. Additionally, ensure that your finger is dry and that you are placing it correctly on the sensor. Sometimes, slight movements during scanning can affect recognition.
Another reason could be the quality of the fingerprint registration itself. If you registered the fingerprint with your finger at an awkward angle or not securely placed on the sensor, it might not capture the necessary details. To resolve this, consider deleting the current fingerprint and re-registering it by following the proper scanning technique, ensuring complete coverage of the sensor.
What should I do if I forgot my password or PIN for fingerprint access?
If you’ve forgotten your password or PIN used to access fingerprint settings on your Samsung S21, you will need to reset it to regain access. If you have previously set up Samsung’s Find My Mobile or any other recovery method, you can utilize those options to reset your PIN or password. Simply follow the prompts on the recovery page to reset your credentials securely.
Alternatively, if you cannot recover your password or PIN, you may have to perform a factory reset of your device. However, keep in mind that this will erase all data on your phone, returning it to its original state. It’s crucial to back up any important information before proceeding with a factory reset to avoid losing any data permanently.
Is fingerprint security on the Samsung S21 reliable?
Fingerprint security on the Samsung S21 is generally considered to be reliable and secure for everyday use. Samsung employs advanced technology to ensure that fingerprint data is securely stored and processed directly on the device, enhancing security against unauthorized access. The biometric sensor is designed to recognize your fingerprint quickly while reducing the likelihood of false matches.
However, no security system is infallible. For added layers of security, consider complementing fingerprint authentication with other methods such as PINs, patterns, or facial recognition. This can provide an extra layer of protection for your personal data, especially if the smartphone is lost or stolen. Always keep your software updated to benefit from the latest security improvements.
