Battle.net FAQ

Q: What is Battle.net?
A: Battle.net is Blizzard’s free online account system that lets players manage all of their Blizzard Entertainment games, including World of Warcraft, in one place without having to remember multiple sets of login information.
Q: How is the World of Warcraft Starter Edition related to Battle.net?
A: When signing up for a World of Warcraft Starter Edition, you create a Battle.net account. You use your Battle.net account name and password to play World of Warcraft.
Q: What can I do with a Battle.net Account?
A: After creating a Starter Edition account, your Battle.net account simply allows you to play the World of Warcraft Starter Edition. If you enter your contact information on Battle.net, you will be able to access extra features. You can make purchases at the online Blizzard Store, keep track of CD keys for your Blizzard Entertainment games, access our websites, opt in to upcoming beta tests, and more using a single login -- just your email address and a password.
Q: How do I access the extra features of my Battle.net account?
A: To unlock the full functionality of the Battle.net account, head to http://www.battle.net and log in. Then, in the screen that appears, enter the requested contact information. That’s it!
Q: Is there a subscription fee or a creation fee?
A: No, there is no subscription or creation fee for creating a Battle.net Account.
Q: My family would like to try World of Warcraft together. Should we create a single Battle.net account for all of our World of Warcraft Starter Edition accounts?
A: No. Sharing access to a World of Warcraft account, other than by a parent or guardian with a single minor, is a violation of World of Warcraft’s Terms of Use. You should create a separate Battle.net account for each family member’s World of Warcraft account.
Q: Can I add more than one World of Warcraft Starter Edition to a Battle.net account?
A: Yes, although only one of those accounts can play the game at any given time. After you log in to World of Warcraft using your Battle.net account, you will be prompted to select which of the World of Warcraft Starter Edition accounts you wish to play.
Q: I already have a classic Battle.net account that I made for StarCraft, Warcraft III, and/or Diablo II. Can I just use that?
A: No, the new Battle.net Accounts are separate from classic Battle.net accounts for StarCraft, Warcraft III, and Diablo II. To allow for the Battle.net features we have planned, we’ve built the new Battle.net Account system from the ground up for World of Warcraft and our future games. In order to play Warcraft III, Diablo II, and StarCraft on Battle.net, you will still need to log in using your “classic” Battle.net login information.
Q: What happens if I change my email address?
A: If you change your primary email address in Battle.net Account Management, the Battle.net Account name will change automatically, and you will log in using the updated email address. Your World of Warcraft Starter Edition account will be unaffected.
Q: Can I log in to Blizzard Entertainment forums after creating a Battle.net Account?
A: Yes, you can access the World of Warcraft forums with your Battle.net account. To access the classic Battle.net forums (including the existing StarCraft II and Diablo III forums there), you will continue to log in as you have in the past.
Q: Isn't it a bit risky to link all my games to one password? What if someone steals my Battle.net account?
A: Security has always been one of our top priorities, and that’s true of Battle.net Accounts, too. For related information and security advice, please visit http://us.blizzard.com/support/article.xml?articleId=26328.
