With the Battle.net Authenticator and Battle.net Phone Notifications enabled, you'll receive the feisty fiery Core Hound Pup, an account-wide pet*. After attaching a Battle.net Authenticator, the Core Hound Pup will automatically be added to your in-game Collection. You'll also gain four extra bag slots*—account-wide—in each character's main backpack.
