Reminder: Battle.net Authenticator Migration
Blizzard has sent emails regarding the Battle.net Authenticator Migration, reminding players to download the new Battle.net Mobile App by January 5, 2024 to avoid any issues logging in.

Players that choose not to install the new app will have the authenticator removed from their accounts, and they will no longer be protected or able to approve login requests. The account's password will also be reset, and instructions on how to set up a new password will be sent to the registered email inbox.

Migrating An Authenticator

If you currently have your Battle.net Authenticator in the Battle.net Authenticator App, you should migrate to the new Battle.net Mobile App now! Once you migrate to the new app you should remove the legacy Authenticator app from your device as the codes will no longer be usable. When migration becomes required on January 5, 2024, users who have not yet migrated will have their old Authenticator removed from their account and will receive a password reset to their registered email inbox. Until the Authenticator is active in the Battle.net Mobile App, users will lose access to the perks associated with having an Authenticator on their account such as the Corehound pet, extra bag slots, and access to LFG features.

Managing An Authenticator

If you have never used an Authenticator, or had an old Authenticator, additional details and information on installing and setting up your Authenticator in the Battle.net Mobile App can be found on our support article, Battle.net Authenticator. If you need to remove an old Authenticator from your account, follow the prompts here to remove your Authenticator temporarily.

Can't Access My Account

If you are unable to access your account at all, follow the steps here to recover your account credentials.

If you no longer know the password to your account, it can be reset by following the steps on our support article, Forgot Password.

FAQ

Can I use the same Authenticator Serial Number to secure more than one Battle.net Account?

The Battle.net Authenticator requires a phone number be attached to an account, and a phone number can only be attached to a single Battle.net Account.

Can I set up the same Authenticator Serial Number in more than one smartphone?

Your unique Authenticator is tied to your mobile device and we do not support setting up the same Serial Number on more than one device.

I don't have a mobile phone number

A mobile phone number is required to set up and use the Battle.net Authenticator. If you are unable to access your previous Authenticator contact support.

I'm not receiving the text message during setup

Battle.net Phone Notifications are designed for text-enabled mobile phones. Messaging apps like iMessage (iOS) or WhatsApp (iOS, Android) are not supported. Phone notifications cannot be used with Voice over IP (VoIP), and VoIP numbers that are transferred to a local provider are not eligible for the service.

I have a physical Authenticator. Can I still set up an authenticator in the Battle.net Mobile App?

Before you can attach the mobile Battle.net Authenticator you will need to remove the physical authenticator from your account.

    Odd - when I open up the battle net app for the first time (on a new device) - all you get is the login screen.

    Google/Open/MS authentictors are all outside the apps that use them.

    I swear they need a button on these forums that has a Bitch Slap feature to slap people like you.

    So dumb.

    The thing is: i am using a Huawei phone and i don't have access to Google Play. And this app doesn't exist in Huawei's AppGallery! I am using physical authenticator since it is implemented in game (maybe for 15 years dunno) So now they will cancel my physical authenticator and force me to buy a new phone to download that app? Gj blizzard, i was looking for a reason to quit wow now you are quitting me, really gj...

    At least they thought of removing the authentication from accounts rather than making them inaccessible.

    Does this only apply to people who use an authenticator or will an authenticator be required from now on?

    Thank the sea! I don't have a phone that supports apps right now. (Honestly, I can get one but I'm lazy, and don't need to take my internet addiction on the road)
