The Samsung Galaxy S21 is a powerhouse of a smartphone, packed with cutting-edge features and advanced security options. One of the most convenient and secure ways to unlock your device is through fingerprint recognition. However, the default setting only allows you to add up to three fingerprints. But what if you want to add more? In this article, we’ll explore the possibilities and provide a step-by-step guide on how to add more than three fingerprints to your Samsung Galaxy S21.
Understanding Fingerprint Recognition on the Galaxy S21
Before we dive into the process of adding more fingerprints, it’s essential to understand how fingerprint recognition works on the Galaxy S21. The device uses an ultrasonic fingerprint sensor, which is embedded under the screen. This sensor uses high-frequency sound waves to create a 3D map of your fingerprint, providing an accurate and secure way to unlock your device.
The fingerprint recognition system on the Galaxy S21 is highly advanced, with features such as:
- Fingerprint spoof detection: The sensor can detect and reject fake fingerprints, ensuring that only authorized users can access your device.
- Multi-angle recognition: The sensor can recognize your fingerprint from different angles, making it easier to unlock your device even when your finger is not directly on top of the sensor.
- Anti-spoofing technology: The sensor uses advanced algorithms to detect and prevent spoofing attacks, ensuring that your device remains secure.
The Limitations of the Default Fingerprint Setting
By default, the Galaxy S21 allows you to add up to three fingerprints. While this is sufficient for many users, it can be limiting for those who want to add more fingerprints for convenience or security reasons. Perhaps you want to add a fingerprint for a family member or a trusted friend. Whatever the reason, it’s essential to know that there are ways to add more than three fingerprints to your device.

How do I add more than 3 fingerprints to my Samsung Galaxy S21?
To add more than 3 fingerprints to your Samsung Galaxy S21, you’ll need to enable the “Advanced fingerprint” feature. To do this, go to the Settings app, then select “Biometrics and security,” and finally, tap on “Fingerprints.” From there, toggle on “Advanced fingerprint” to enable the feature.
Once you’ve enabled advanced fingerprinting, you can add up to 5 fingerprints to your device. To add a new fingerprint, follow the same process as you would for adding a standard fingerprint. Simply place your finger on the fingerprint sensor, and follow the on-screen instructions to register your print.
What are the benefits of adding more than 3 fingerprints to my Samsung Galaxy S21?
Adding more than 3 fingerprints to your Samsung Galaxy S21 provides an additional layer of security and convenience. With more fingerprints registered, you’ll have more flexibility when it comes to unlocking your device. For example, if you have a fingerprint that’s more easily accessible, you can use that one instead of having to contort your hand to reach a specific finger.
Additionally, registering multiple fingerprints can help to reduce the risk of false rejections. If one of your registered fingerprints is dirty or damaged, you can use another one to unlock your device. This feature is especially useful for people who work with their hands or are frequently exposed to substances that can damage their fingerprints.
Will adding more fingerprints to my Samsung Galaxy S21 affect the device’s performance?
Adding more fingerprints to your Samsung Galaxy S21 will not significantly affect the device’s performance. The fingerprint sensor is designed to handle a certain number of prints, and adding more fingerprints won’t slow down your device or drain the battery.
In fact, the advanced fingerprint feature is designed to work seamlessly with the device’s existing hardware. The sensor is capable of handling multiple prints quickly and accurately, so you won’t notice any delays or lag when unlocking your device.
Can I add fingerprints from multiple people to my Samsung Galaxy S21?
While it’s technically possible to add fingerprints from multiple people to your Samsung Galaxy S21, it’s not recommended. The fingerprint sensor is designed to recognize the unique characteristics of an individual’s fingerprints, and adding prints from multiple people could lead to confusion and false rejections.
Additionally, allowing multiple people to access your device using their fingerprints could compromise the security of your device. It’s recommended to keep your fingerprints private and only grant access to trusted individuals.
How do I delete or edit fingerprints on my Samsung Galaxy S21?
