- Were you looking for the Battle.net Mobile Authenticator (mobile smartphone application)?
The Battle.net Authenticator (previously called the "Blizzard Authenticator") is a small device (fits easily on a keyring) that enables you to secure your account by an additional code, consisting of 6 digits. As of 2015, Blizzard support may refer to the mobile app interchangeably as the "Battle.net Authenticator".
As explained in the old Authenticator FAQ:
- How does the Battle.net Authenticator work?
- You must first associate the Battle.net Authenticator to the World of Warcraft account you play. Once the account has been linked, the Authenticator token will be required to log in to Account Management or to the game; when logging in, you will be prompted to supply a digital code generated by the Authenticator.
This device is a custom manufactured VASCO Digipass GO 6 device.

Logins affected by the authenticator
Recent changes have occurred that means players may not be prompted to input their authenticator code every time they log in:
Need to disable lost authenticator
The Authenticator can stop working as intended, showing a "Disabled" message on the display instead of the random 6 digits code, becoming useless. The button becomes unusable and the displayed message will not disappear.

There are reports on the official forums about other authenticators malfunctions like being stuck on the 6 digit code or generating random letters+numbers codes that doesn't work. The one pictured above and to the right worked for 2 weeks before it malfunctioned.
There have been reports of compromised accounts having an authenticator added to prevent the true owner regaining access to their account and preventing the sale of items.. This may be due to a zero-day attack that may not yet be picked up by your anti-virus or Spybot S&D etc. If this happens, you are recommended to follow the advice posted by Blizzard on their technical support forums, Account Security.
