When I log in Warcraft is asking me for a Battle.net Authenticator number...but I never got an Authenticator so I never got this number. I checked my emails and saw nothing about it either.

So yeah...help please.

Unfortunately, if you are being prompted to enter an Authenticator key, it is likely that your account has been accessed by a malicious party who has attached an Authenticator to your account to restrict your access. Accordingly, it is of utmost importance that you secure your computer to ensure that you do not have any malicious software installed on your computer. For more information on how to secure your computer and how to avoid phishing scams, please review the following resources:
