We are storing more and more valuable information on our mobile devices. Therefore, it is necessary to have authentication systems that prevent other people from accessing our data. In recent years, manufacturers have seen biometric security methods as the ultimate solution to this problem. If you want to protect your terminal, we recommend that you activate, at a minimum, fingerprint unlocking. In this article, we show you all the steps you must take to do it easily.

First of all, ask yourself: does my device have a fingerprint sensor?

Before setting fingerprint recognition as an unlocking method on your device, you must ensure that you have the necessary hardware. It is true that today the fingerprint sensor is being incorporated in most terminals, even in those that are in the low range. However, it is possible that some specific models do not have the necessary component.

In the market you can find two types of finger sensors. One is located in the back or front, but off the screen. These are usually circular in shape and create a small cavity in the body of the phone. It may also be located on the side power button. On the other hand, some models incorporate it under the screen. In that case, it is more difficult to check where it is located. Check the manufacturer’s manual to verify. Do not forget that, although it is very common to have a fingerprint reader in mobile phones, Android tablets do not usually incorporate this type of hardware. In that case, it will be impossible for you to use your fingerprint to unlock the device.

How to set up the fingerprint sensor on your Android phone

If, fortunately, you have a fingerprint sensor in your terminal, go to the Android settings and locate the option Security. Click on it to access.
