It is possible to put a password on the applications to protect information on Android, including what is saved on Facebook, WhatsApp and the photo gallery of the cell phone. To do this, simply use the encryption locking tools that prevent the viewing of sensitive files. Among the options downloaded from the Google Play Store, we chose three free tools to help you choose.
Next, see the main functions of the App Lock, AppLock and WhatsLock apps, and decide which one best suits your smartphone security needs. Even with a few different features, these three apps offer features to prevent break-ins and theft of personal data.

App Lock is an application that has powerful features to ensure data security on your smartphone. In addition to the standard lock (drawing), it allows the user to configure the front camera to capture images of intruders trying to overcome the password lock. This function is useful for identifying people who stole your cell phone, or even curious friends and family.
After installation, just select the apps that will receive password access. In addition, the tool also allows you to choose a custom background for the lock screens and can be configured to work in the background.

The AppLock Lock allows you to define a password for accessing messengers and social networks installed on the cell phone. To use, it is necessary to choose the applications that will receive the encryption, creating a code to unlock. When activating the feature, the user must enter the password to access the selected apps.
This application does not offer many configuration possibilities. There is no option to use the camera to capture faces, for example. Still, it works well to prevent confidential conversations on messengers from being displayed on the screen.

WhatsLock is a paid tool that brings advanced security management to apps on Android. It allows users to use a code (password or pattern) to block access for messengers, social networking apps and mobile settings. It also draws attention to the possibility of hiding images, videos and a tool to delete confidential files.
Professional features keep WhatsLock ahead of its competitors. However, I need to consider whether it is worth paying for one of the plans to use the software options.
