The first thing you'll be asked to do is input the account you wish to use for the Master Account. This is the password you will use to get into the program so that you can create your hidden folder list and make your folders hidden or visible.
IMPORTANT: Passwords are the weak link in any security system. There are programs out there that can guess passwords in a relatively short time. To prevent such programs from guessing your password make sure your password is at least 10 characters long.
