Blizzard authenticator

Blizzard Authenticator is a security feature offered by Blizzard Entertainment to help protect user accounts from unauthorized access. It is available as a physical keychain fob or as a mobile app for iOS and Android devices. The authenticator generates a unique code that users must enter along with their password when logging into their Blizzard account. This two-factor authentication method adds an extra layer of security to help prevent unauthorized access, especially in cases where a users password may have been compromised. The Blizzard Authenticator is highly recommended for all Blizzard account holders to help keep their accounts secure.
