This utility scans the passwords stored by popular Windows applications 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. You can use this tool to determine whether the passwords used by other users are secured enough, without watching the passwords themselves.
Currently, Password Security Scanner scans the passwords of the following applications:
Internet Explorer 4.0 – 6.0
Internet Explorer 7.0 – 9.0
Mozilla Firefox (All Versions)
Dialup/VPN passwords of Windows
Windows Live Mail
Support for more applications will be added in future versions.
