I'm looking for either option A or option B.
A) An application that requires a passcode to open, and view apps(that were otherwise hidden before, using Nova Launcher). It acts like the private picture gallery, but instead its an app directory.
B) A way to set a password to folders in Nova Launcher.
I know there's Guest Mode now, but it goes to factory stock. I don't want people to even know I have these specific apps, not even a visual of the icons for the apps.
