How to protect your applications with a fingerprint

Do you want to protect applications full of private data on your Android phone? You can use the fingerprint to protect them. Find how! The fingerprint sensor has become essential for Android phones. More and more devices have one, and there has also been an important evolution in the types of sensors in the devices over time. 

The most common is the one found on the back, but more and more mobile phones integrate it on the screen. The fingerprint can be used for many functions.

We usually use the fingerprint to unlock the phone, but there are more options available. For example, applications can be blocked thanks to the footprint. In this way, the app will be executed only when the user’s fingerprint is detected, preventing people without permission to access it.

Protect applications with a fingerprint

Typically, an average user has a huge amount of data stored on their Android phone. Photo, password… it is also possible that there is banking information. Therefore, it is not convenient for anyone to have access to such information. Protecting or blocking applications with a fingerprint is a good solution.

It allows nobody, except the user, to access this function. Therefore, this simple gesture can be a good way to protect the information stored on the phone. Improve security and privacy in just a few steps.

Below is the complete list of applications installed on Android. Next to each of them, there is a switch, your phone offers you the possibility to lock with the fingerprint only the ones you want. By doing this you have ordered by phone which applications need to be protected with a fingerprint. Next time, when you access one of them, you will be asked for a fingerprint or a security PIN.

It is likely that the Android smartphone you own does not offer this feature natively. As long as you have a fingerprint sensor on your device, you can use applications that offer this possibility. There are many available in the Google Play Store.
