Api.wordpress.org Secret key URL

As it says in the default wp-config.php of a WordPress installation:

    /*
    * 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
