Software to retrieve passwords (and usernames) that are stored in our web browser(s) may be looked upon as software that could be used for malicious and/or forensic purposes. There is some truth to that; however, I had an occasion recently where I used this type of software to do a good deed for a person.
WebBrowserPassView is a password recovery tool that reveals the passwords stored by the following Web browsers: Internet Explorer (Version 4.0 – 11.0), Mozilla Firefox (All Versions), Google Chrome, Safari, and Opera. This tool can be used to recover your lost/forgotten password of any Website, including popular Web sites, like Facebook, Yahoo, Google, and GMail, as long as the password is stored by your Web Browser.
