Can't go in the Admin CP

[Flumuffel]

When I would login me in the Admin CP then I need a Secret Pin but I have never edit this Secret Key and now I can't go in the Admin Panel. How can I change that Pin and how?

Here is a Screenshot of my Website

You must go into your website folder area and go to the root (maybe public_html)/inc/ and locate a file named config.php and modify it as shown in the screenshot below.
