If you want to keep your Scroll secure and not allow others to open/ run/ install/ uninstall/ view etc... this provides a very flexible way to secure what Apps can be opened by protecting the App with a password. You can choose your new PWD of choice, Hint for PWD and e-mail the new PWD just as you set it up there and then
It does add a set amount of Apps that are PWD protected after install. You can remove PWD protection for any App or add an App that you want to protect by prompting PWD before opening the App.
Apps to password protect: (my suggestion)
Browser (if you keep auto logons of passwords)
Settings
Camera
Gallery
E-mail
G-Mail
Startup managers
File explorers
App Killers
App Uninstallers
Remote access Apps
Be warned though, it will prompt you when using e-mail for the PWD for each new mail you want to read. You can turn off the PWD for any App if you find it to intrusive
