The modern browsers are coming with many useful features which make our browsing experience better. One feature that I think most useful their ability to store passwords or login information. You might have noticed that browser asking for remembering password when you login to a site. If you select remember option in the browser, you can directly login next time you visit the site without entering login details.
After a long run, when you need to enter your password on other system, you may not remember the password you have set. Your password is stored in the browser but you cannot see your password directly. Using password recovery tools you can retrieve passwords stored in the browser easily, even if you have forgot master password.
