Windows Phone has at last got its official Steam app. "Hold the press," you say. "That'll be big news for all four people with a Windows phone, but why are we talking about apps?" Well, this "initial, limited functionality, release" plugs a substantial gap in Valve's campaign to get everybody using Steam Guard two-factor authentication.
Last year, Valve introduced 'trade holds' to slow down the spate of virtual item theft. Traders using Steam Guard to verify their identity bypass the 15-day hold. Until now, however, there was no mobile authenticator for Windows Phone users, making trading a right hassle.
