This utility scans the passwords stored by popular Windows applications (Microsoft Outlook, Internet Explorer, Mozilla Firefox, and more...) and displays security information about all these passwords. The security information of every stored password includes the total number of characters, number of numeric characters, number of lowercase/uppercase characters, number of repeating characters, and password strength.
