How to Recover a lost password of your facebook account
If you can't remember the login password of your facebook account, there is still a chance that you can easily recover your lost password, as long as the password is stored in your computer by the Web browser you use.
You can try to recover your facebook password by using the WebBrowserPassView utility. This utility can recover the password from 4 different Web browsers - Internet Explorer, Firefox, Opera and Google Chrome. You can download this utility directly from this link.
After you download it, open the zip file and run the WebBrowserPassView.exe executable. Be aware that because this utility can extract password from your system, your Antivirus software may display an alert and even block you from running this .exe file.
After running WebBrowserPassView, the main window will display all the passwords stored by your Web browser. In order to find your facebook password, you have to locate the record line where the URL is http://www.facebook.com or http://www.facebook.com/login.php
If you located the correct facebook record, the password that you need will be found under the 'Password' column, as you can see the in the following sample screenshot:
If you can't find any record with facebook link, your facebook password is probably not stored by your Web browser. Also, be aware that WebBrowserPassView cannot locate your password if it's protected by a master password, or if it's stored by a Web browser other than Firefox/IE/Opera/Chrome.
