The pin locker app is designed to be one place where you can safely store all your usernames, passwords, PINs and other information which you need to have but can't let fall into the wrong hands. This app is very simple to use, when the app opens you have to put in your password (so you have to remember that one!) and then you can see all your other information organized for you. With today's high tech world which requires a password for just about everything, this is a great way to keep them all organized and in one place so they are easy to find.
