The time has come to migrate your Authenticator from the old Authenticator App to the new Battle.net App. If you currently are using the Battle.net Authenticator app, you must migrate to the new Battle.net mobile app by January 5.

Migrating Your Authenticator to the Battle.net Mobile App

The Authenticator feature is now available in the Battle.net mobile app. The old Authenticator app will be removed from all app stores as early as January 1, 2024, and will no longer be available for download. Players who migrate their authenticator will be able to continue using the Battle.net mobile app to authenticate their account logins.

If you currently have your Battle.net Authenticator in the Battle.net Authenticator app, you must migrate to the new Battle.net mobile app by January 5. After this date, we will begin removing the authenticator from accounts which haven’t migrated, reset passwords for affected accounts, and notify all affected players of the reset.

Once you migrate to the new app you can remove the legacy Authenticator app from your device. Learn more in our support article.

Where Can I Get the Battle.net Authenticator?

Don’t have an Authenticator on your account? Download the free Battle.net mobile app for iOS or Android, Visit the Battle.net Authenticator article for more information, or head to the setup page to get started after you’ve downloaded the app.

As an additional bonus, when you add an Authenticator to your account, you’ll find the always feisty and fiery Core Hound Pup* in-game pet waiting for you.

What are Battle.net Phone Notifications?

Battle.net Phone Notifications let you perform certain account actions from your mobile phone (such as removing your Authenticator) and can be set up to provide you with account activity notifications. All you need is a supported text-enabled cell phone to get started.

What can Battle.net Phone Notifications do for you?

• Unlock your Blizzard account
• Remove a lost Authenticator
• Recover your account name
• Reset your password

In addition, you can turn on alerts to have text messages sent directly to your phone notifying you of certain kinds of account activity, like password changes and security feature additions or removals. These text messages are an easy way to help protect your account from unauthorized access and changes.

Remember, you can further safeguard your account by never sharing your password, using unique passwords on each site you visit, and staying aware of potential email and phishing scams.

We take account security seriously, and we know you do, too. So, when you add an Authenticator—now available with the Battle.net App—along with Battle.net Phone Notifications to your account, you’ll gain four extra bag slots*—account-wide—in each character’s main backpack in World of Warcraft. You’ll be able to hold a little more stuff as you adventure through Azeroth and keep that stuff safer from scoundrels and thieves.
