® SMS Protect

Keywords:® SMS Protect helps you manage your account. With it, you'll receive helpful notifications when important changes are made to your account. Any standard cell phone in a supported country with a data plan may be used as a SMS Protect device. SMS Protect has two key features:


The SMS Protect service sends a text message to your cell phone if important changes are made on your account. You'll receive texts when your password is changed and when account security features are added or removed.

Note: Notifications are disabled by default and must be enabled manually through account management.

Security codes

When an account change is initiated, the service sends a unique security code via text message. This code is required to complete whatever change is in progress. Security codes will be sent when you try to:

  • Unlock your account using your mobile phone.
  • Remove an unwanted authenticator from your account.
  • Recover your account name.
  • Reset your password.

Eligibility & Limitations SMS Protect is designed for text-enabled cell phones. You can link a account to a single mobile number for SMS Protect. The service is provided by Blizzard completely free of charge. Your phone carrier's standard rates for text messages apply. If you are unsure if you have a text or data plan, contact your phone provider.

  • SMS Protect messages are sent via text, so messaging apps like iMessage (iOS) or WhatsApp (iOS, Android) are not supported.
  • SMS Protect is not currently available in all countries. The service is expanding and more countries will be added soon.
  • Cell phones with prepaid plans may not work with the SMS Protect service.
  • SMS Protect cannot be used with Voice over IP (VoIP), and VoIP numbers that are transferred to a local provider are not eligible for the service.


You can change or remove the service from the SMS Protect page. If you have SMS Protect but are unable to receive the SMS verification code, contact your phone provider for assistance.

If you lose your phone but plan to replace it and keep the same mobile number, you don't need to do anything! SMS Protect will continue to work as it has before, since it is associated with your phone number rather than the device itself. If you lose your phone and don't plan to replace it, or if you want to remove SMS Protect while you find a new phone, submit a ticket so we can assist you.
