Steam Guard Goes Live for All Users
Steam Guard, Valve’s new security measure for Steam, has now been activated on all Steam clients. The security system gained worldwide attention when Gabe Newell made his own username and password public to show how secure Steam Guard is.
Basically, Steam Guard ties your Steam account to a specific PC. Any future attempts to access it from another PC generate an email to the account holder asking for permission. Steam Guard is planned to utilize Intel’s new Identity Protection Technology, but this functionality is not yet included.
Steam Guard will be automatically installed in the next Steam client update you download. If you’re not keen on using it, you can go into your Steam settings to deactivate (or reactivate) it at any time.
