The application is a big scam. If you access it and press the CTRL + U while it calculates the password, you'll see a progress_bar divID. Furthermore, clicking on the script.js in the source code reveals that the progress bar is automatically generated using Java code.
Secondly, those offers are meant to trick you as the password can't be guessed this easy. I even added a valid username and still calculated the password.
Please avoid such things as they're fake and they're developed to trick you. The developer gets a high amount of money after you complete that offer.
