This software offers both password sniffing and recovery capabilities in one easy-to-use package, making it simple to uncover and retrieve lost passwords across a variety of platforms.

Currently, Password Sniffer Spy supports multiple protocols such as HTTP (BASIC authentication), FTP, POP3, IMAP and SMTP. It is a great tool not only for recovering your own lost passwords, but also for various scenarios such as running it on Gateway System where all of your network's traffic pass through, performing a MITM Attack, or running it under Administrator account to silently capture passwords for all the users in a multi-user system.
Moreover, Password Sniffer Spy comes with an installer that installs the Winpcap network capture driver required for sniffing. For Windows 8, you have to manually install the Winpcap driver (in Windows 7 Compatibility mode) before using it.
One thing that impressed me about Password Sniffer Spy is that it works on both 32-bit & 64-bit platforms starting from Windows XP to Windows 10. It is a great software that can offer security for your login passwords and capture them in case of emergency. Overall, I would definitely recommend it to anyone who needs to monitor their network activities.
Version 6.0: Major release with new installer for easier installation & un-installation. Also added download links for Winpcap drivers.
