13	13	* Since the parameters are documented as strings in various places (`wp_authenticate` action, `secure_signon_cookie` filter, `wp_authenticate()` function, `authenticate` filter, etc.) is seems like a bug that they are created as `null` instead of an empty string. Documenting `null` as a possible value does not seem ideal, as it forces plugins to deal with the issue on their own instead of fixing it at the source.
