Is it possible to attach a game's authentication key to multiple Battle.net accounts?

Say I have a Starcraft II: Wings of Liberty authentication key. Can I create a new Battle.net account, attach that key to it (register/activate it). Then, if need be, un-register it from that account, and attach that same key to another Battle.net account?

  • You are referring to CD keys (game licenses), and not Blizzard Authenticators (security token generators), correct?

  • Correct, cd keys is what I mean. Although, on the actual game box, the term used is "Authentication key".

  • Game keys cannot be attached to two battle.net accounts. (trying to do so gives a message saying that that key is already in use)
  • Game keys cannot be unregistered or transferred by any user options. (The interface has nothing of the sort)

If this needs to be done, you'd have to contact Blizzard customer support, but I'm not sure they'll let you. They might though.


After re-reading through the TOS, there are two separate "licenses" involved (from a legal perspective), the license to use the game client, and the account to play with. The account cannot be sold. The client can be transferred, but the new owner would have to purchase a new account, that is supposedly available at blizzard.com or battle.net

(I am not a lawyer, my advice is not legal advice)

    does that implicitly mean, I can't sell the game?

  • Do you have a link to where you found those bullets?

  • I tried to source those bullets with the stuff in parentheses, it's not amazing sourcing, but it's the best I can come up with.

  • And yes, that does mean that you can't sell the game. But IIRC, the terms of service does mention how transferring an entire account would work. Again, for something like that, I'd recommend talking to a Blizzard customer support representative to take care of it.

    @Mechko the physical product does not contain the full IP, it requires an online component. If I shipped you a twitter client, I could not guarantee IP rights to twitter as I do not own twitter. The disc does contain IP rights to the client, but not to the online service.
