Move Diablo IV To Another Battle.net Account

You cannot move a Diablo IV account from one Battle.net account to another, or merge two Diablo IV accounts into a single account.

If you own more than one Battle.net account and you'd like to play or chat on several accounts at the same time, you can turn on the option to run more than one Battle.net App at the same time in the App Settings:

1. Open the Battle.net desktop app.
2. Click the Blizzard icon in the upper-left corner and select Settings.
3. Under the General tab, tick the Allow multiple instances of Battle.net box
4. Click Done.
