Why the portal lets you back in

My first thought is the WIFI system must remember MAC Address of the machine. However, after changing MAC address, it still remember my machine. Then another option would be web browser sent cookie value to identify itself, and the WIFI system uses cookie value to identify which machine has already used free Internet. Thus, using Private mode>portal.boingohotspot.netwebsite.
