The number of MMORPG games online has grown phenomenally over the past decade with millions of players who have invested countless hours in creating their characters and developing them to the highest levels. To the outsider this may not seem like much, but to the gamer this is very important and as such so is the security of their account. Many gaming companies have switched to using single sign on authentication to help protect these accounts.
The most common form of single sign on authentication currently being used by online game companies is the RSA token. This can be a physical device that displays a randomly generated short lifespan number such as those available from Digi-Sign or an application for a device like a smartphone or a tablet PC. With the average high level gamer account worth hundreds if not thousands of dollars on the black market, this type of security is vital to protecting them.
