If you are an avid consumer of games from Blizzard, such as World of Warcraft, Overwatch, Hearthstone, Diablo 3, or StarCraft 2, securing your account should be a top priority. While having a username and password is essential, it isn't foolproof against hackers. The best way to ensure that your account remains secure and your game progress and investments are protected is to enable two-factor authentication (2FA) for your Battle.net account. Blizzard provides a mobile app called Blizzard Authenticator and an SMS protection feature called SMS Protect. Here’s how to enable and use 2FA for Blizzard's games:

Once logged in, click on your account icon in the top-right corner and select Account Settings.

Navigate to Security & Privacy

After installing Blizzard Authenticator on your smartphone, return to your web browser and click on "Set up your authenticator" on the "Add an Authenticator" page.

Verify Your Email
Verify your email by clicking Continue. Blizzard will send a security code to your email, which you will need to retrieve and enter in the Security Code field.

2. How to Use Two-Factor Authentication (2FA) to Log In to Your Blizzard Account, Using Blizzard Authenticator
After enabling 2FA, you will need to approve each login attempt. Enter your username and password as usual, then open the Blizzard Authenticator app on your smartphone and tap Approve, ensuring the codes match before confirming.
