SterJo Instagram Password Finder is small and easy-to-use tool developed to recover the forgotten password of your Instagram account saved by web browsers. The application currently is able to retrieve login details stored by Google Chrome, Mozilla Firefox, Internet Explorer and Opera.
The interface of the program is simple where the main window displays details about each account which could be copied to the clipboard.
NOTE: This is not an instagram password hacker nor even an instagram password cracker and it should be used only to recover your own forgotten instagram login stored by the web browser.
