The new feature will allow users to link account management options to a specific machine; an extra measure to prevent unauthorised access. Steam Guard will also notify you if any PCs attempt to log in to your account. The feature will be available for third parties to use.
Steam Guard will take advantage of upcoming Intel® Identity Protection Technology (Intel® IPT), an encrypted, hardware-based feature available with the new 2nd Generation Intel® CoreT and Intel® CoreT vProT processors.
Valve’s president, Gabe Newell has said “”Account phishing and hijacking are our #1 support issues. With Intel’s IPT and Steam Guard, we’ve taken a big step towards giving customers the account security they need as they purchase more and more digital goods.”
