Customer’s guide on securing a battle.net account

In this guide, we’ll go step by step on how to fully secure a purchased Battle.net account

To take full control of a battle.net account, you need the following information:

Account username (email)
Account password
There must not be phone number or authenticator linked
At least one of the following:
*Access to the email account
*Knowing the secret answer

Then you need to do the following:

Change the email
Change the password
Change the secret answer
Make sure that there’s no phone and authenticator added
Terminate sessions
Unlink accounts
Revoke access from apps
Remove saved payment methods

Below is a step by step tutorial with images, on how to easily do all of that.

Step 1:

Go to eu.battle.net or us.battle.net and log in to the account using the provided email and password.

It will ask for a security check, where you can pick between a code sent to the current email or the answer to the secret question:

Step 2:

Once you’re logged in, open the account overview page (account.blizzard.com/).

On the left, click on the “Account Details” tab. Here, you can modify the email of the account by clicking on the “Update” button on the right. It will just ask you to type in a new email and once you click save, the email will be changed.

The email will be marked as “Unverified” and you’ll receive a message with a verification link which you can click to make it verified. Verifying the email is optional and there’s no downside to keeping the email in the unverified state. The account will work the same.

On the same page, check the “Phone number” section to make sure that no phone is added. If there’s no phone, there should just be a blue “Add Phone Number” link.

Step 3:

Click on the Security tab on the left.

Change the password by clicking on the Update button on the right. It will ask you to type in and confirm a new password, as well as to provide the old. After clicking on Save the password is changed.

Make sure the blizzard authenticator status is “Inactive”.

Click on Update next to the secret question. You’ll be presented with a set of 6 questions and will be asked for an answer to the one you choose.

Click on the “Log out from all devices” button. This will terminate all existing sessions, both for the games and for account management.

Step 4:

Click on the “Connections” tab on the left.

Connected accounts allow you to log in to the battle.net account without knowing the username or password. They provide full access to the account and are basically a backdoor to the account. You must remove all those links for your account to be secured.

Disconnect all connected accounts by clicking on the “Disconnect” button next to each one that’s linked.

You can also revoke access to applications, by clicking on the “Remove” button next to each. Applications usually don’t have any access to the account, but you can remove them for the sake of just cleaning up the account.

Step 5:

Click on the “Payment methods” tab on the left.

Any saved Paypal accounts and credit cards will be listed here. You should remove all of them by clicking on the Remove button next to each.
