Password Security Scanner is a little tool from Nirsoft that lets you scan your computer for passwords stored by Windows applications and reveal the security information about all passwords. You can use this portable tool to determine the security strength of passwords used by other users of the computer without watching the passwords themselves.

Password Security Scanner reveals the total number of characters, numeric characters, lowercase/uppercase characters and number of repeating characters of each password and calculates the strength of the password.


The following list shows the strength of a password.

• 1 - 7: Very Weak
• 8 - 14: Weak
• 15 - 25: Medium
• 26 - 45: Strong
• 46 and above: Very Strong

Currently this tool supports Internet Explorer (all versions), Mozilla Firefox (all versions), Dialup/VPN passwords of Windows, MSN/Windows Messenger, Microsoft Outlook and Windows Live Mail.

Note: It cannot scan the passwords stored by Firefox if they are protected by a master password. To detect Windows dialup passwords, you need to run Password Security Scanner with administrator privileges.
