Common Problems

  • I created a Hearthstone account on my phone but I can't find it.
  • I started playing Diablo Immortal but lost all my progress when I added an email to my account.
  • I played Warcraft Rumble on my previous phone and I can't find my account.

Guest accounts are automatically created when you launch a game (Hearthstone, Diablo Immortal or Warcraft Rumble) on a mobile device without logging in to an existing Battle.net Account.

These accounts are limited in many ways, including but not limited to the following:

  • Cross-Progression - Because they are not linked to a Battle.net Account, guests accounts cannot benefit from Cross-Progression. Game progress is tied to the device—you'll lose your game progress if you switch devices or you launch the game on desktop.
  • Purchases -  You cannot play on desktop with a guest account or buy on the Battle.net shop with a guest account
  • Friends list - Some games won't allow you to add players to your Battle.net friends list.
  • Diablo Immortal - You'll receive an in-game reward when you link your Diablo Immortal account to a Battle.net Account.
  • Hearthstone - You'll receive a free pack when you link your Hearthstone account to a Battle.net Account.

Due to the above limitations, we highly recommend that you link your mobile game to a Battle.net account.

Link to an existing Battle.net Account

You can only have one Hearthstone, Diablo Immortal, or Rumble game account tied to your Battle.net Account. If you attempt to link a Hearthstone, Diablo Immortal, or Rumble game account to a Battle.net Account that already contains one of those game accounts, you will receive a warning that your new game account will override any data from the old game account. Customer Support cannot assist with recovering lost data.

If you chose to log in to an existing Battle.net Account, you will be presented with the standard Battle.net login screen. Choose from the drop-down below to see the steps next depending on the game.
