What is Intel® Identity Protection Technology?
Intel® Identity Protection Technology (IPT) is a hardware-based security feature available with the new 2nd Generation Intel® Core™ and Core™ vPro® processors. An IPT algorithm runs on the chipset to generate a new numerical password every 30 seconds, integrating into the processor functionality that was previously only available on an external card or key fob.
Steam Guard is a new Steam account security feature offering two-factor authentication. Steam Guard, as demonstrated at CeBIT 2011, can leverage IPT as an additional factor of authentication so access to your Steam account remains in the right hands - yours. With IPT, secondary authentication is effortless, as it is provided by the chipset itself. IPT protects your Steam account against remote takeover, even if your login credentials have been phished, or accidentally shared.
