In WordPress, the wp-config.php file is the file that stores the database information that WordPress needs to connect its circuit, so-to-speak. This file contains the name, address and password of the MySQL database that stores all of your user info, blog posts and other important content.
Using a secret key, you can make it even more difficult for someone to gain access to your account.
