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. 
Despite having so many incredible features, Android phones are not always safe. Persons may hand over their phones to other people for any reason. But the moment they unlock the phone and hand it to someone else, all the data is accessible to anyone who wants to see it. All of your documents and files are accessible to them, along with your photos, videos, and message history.
