Lost Authenticator

Q u o t e:
I need my authenticator disabled because I lost it and I can't buy a new one because it asks me to enter my authenticator code. So if I can get it disabled for the time being, that would be great.

We are unable to process this kind of Authenticator removal via the forums. In a case like this, it will be necessary to contact our Account Services staff directly. You can do so via telephone or email at billing@blizzard.com. If you use email, it may be best to have a Terms of Use form prepared in advance:
