WordPress secret keys and salts

To increase the security of a WordPress site you should add 8 different secret keys to the wp-config.php file.
WordPress has a convenient random secret keys generator wich allows you to copy/paste the keys at
api.wordpress.org/secret-key/1.1/salt/.

/**#@+
 * Authentication Unique Keys and Salts.
 *
 * Change these to different unique phrases!
 * You can generate these using the {@link https://api.wordpress.org/secret-key/1.1/salt/ WordPress.org secret-key service}
 * You can change these at any point in time to invalidate all existing cookies. This will force all users to have to log in again.
 *
 * @since 2.6.0
