The Battle.net® desktop app improves patching and installation and makes login quick and easy with a single sign-on feature. The app handles installing World of Warcraft®, StarCraft® II, Diablo® III, and Hearthstone™ from one central location and it updates your games when a patch is available. You can also use the app’s game pages to stay on top of the latest Blizzard news.
The Battle.net app replaces our previous game launchers. Eventually, all game launchers will be upgraded to the Battle.net desktop app. The app will also act as your gateway to future Blizzard games.
You’ll log in to the app using your Battle.net account information, so it will log you in to all your Blizzard games—you’ll never have to enter your username and password on the game screen again.
If you have Keep me logged in enabled (in Settings > General), the app will keep you logged in for up to 30 days. During those 30 days, you’ll log in automatically if you exit and restart the app.
Installation and Patching
As long as the app is running, it will download and install available patches in the background. The app will only patch one game at a time, and you can manually pause or continue patching in the app. You can also disable auto-patching in the app’s Options menu.
