If you ever forget or lose a website, email, or FTP password, but it’s saved by your computer, you still might be able to recover it.
You can use a utility like SniffPass from NirSoft. It listens to your network traffic and displays any passwords that pass through your network adapter.
Remember, some network sniffers can even capture other users’ traffic. This can be a security or privacy problem, especially when using public network ports or Wi-Fi hotspots. Make sure the sites or services you log into on public networks are secured with SSL encryption.
