Master Password is a freeware software developed for Windows Vista/XP systems. This application helps users to store all their user IDs and passwords in a central location, just like a database. The interface of this utility is simple and easy-to-use with a toolbar to add and edit entries. All the existing entries are displayed in a window. Besides keeping a track of your user ID and corresponding passwords, this application also allows you to add short notes and program paths. The application is password-protected and the passwords are masked by default. However, one of its major limitations is that changes do not require any authorization.
