They could also be doing something like giving the client an SSH key to download, I've heard of this situation in a bank before.
Though it does seem more likely that their just using cookie based authentication --------------------------------------------------------------------- From: "Rahul S.

When you go to their website to login to view your account, they ask you to register your computer for the first time. Once your computer is registered, you can access the account using that computer. You can choose to Not register that computer and you won¹t be able to access the account using that computer in future. What exactly are they doing? Can PHP record the MAC Address of the NIC in the computer? Or are they just recording the IP and creating an IP based filteration? I¹m looking to implement a similar security system for one of my applications. Any advice? Rahul S.
