13 Best Android Apps to Password Protect Files and Folders

Android phones today are continually implementing new technologies in order to protect consumer data. In addition to the traditional password option, practically all phones now include a fingerprint sensor. Some of the advanced features that can be found on higher-end smartphones are face scanners, fingerprint sensors built into the screen, and different encryption options.
