Basic settings for your WordPress website are usually set by a hosting provider without your participation. These settings include the most important data: database name, main user name, his or her password, database host address and table prefix.

define('DB_NAME', 'database-name');
define('DB_USER', 'database-username');
define('DB_PASSWORD', 'database-password');
define('DB_HOST', 'localhost');

To make the changes, you need to download your wp-config.php file with the help of FTP client first. Then, after making the changes, you need to upload the new file and rewrite the old one. To avoid any harm to your website, make the back-up of the original WP-Config file on your local computer.
