AirPort Express Assistant changes the base station password when setting up a WDS remote

If you use AirPort Express Assistant to configure AirPort Express as a WDS remote, it will automatically change the base station password to match that of the WDS main station. This behavior protects the AirPort Express in the event that you still have the default password "public".
AirPort Express Assistant does not have options for defining a separate password for the main and remote stations, but you can customize your password settings using AirPort Admin Utility.
