Update:

Sure enough, Diablo III's real-money auction house is now live.

A guide to using the auction house has been posted on the Diablo forums.

Happy bidding!

Original story:

It looks like Diablo III will finally get its real-money auction house sometime tomorrow, with one extra wrinkle: a Battle.net authenticator will be mandatory for those wishing to use the service.

The auction house will allow players to directly bid on in-game items such as weapons and armour using real, actual money for the first time – officially at least – in the franchise’s history.

A compulsory authenticator is also a first, although it’s worth noting that those with a smartphone can download a free app rather than pay USD$6.50 (AUD$6.60) and wait for Blizzard's plastic token it to be shipped.

Either way, players will need their user name, password, and a verification code to log on to the store – the latter of which is provided by the authenticator.

With the authenticator, “you can rest easy knowing that your account is now even more secure from malicious attacks such as keyloggers and trojans,” stated Blizzard.
