Face Lock Screen is a tool for securing your smartphone. It is based on the face recognition technology to make the smartphone unlockable by just using the user's face. The app is also a password manager, so it can save the passwords of all the apps you use and recall them just in case. You don't need to remember the password for each app, but you can if you wish to do so. You can also use it to secure your social media accounts if you use the same username and password for each account. It also supports fingerprint recognition and pattern lock.

This is a very simple and easy-to-use app, so if you want to try it, you won't have any problem with it.
