Log in failed

Q u o t e:
everytime i try to log into the game it says log in failed. It also does it on the other account we have. When i try to log onto my battle.net account it says log in failed. What gives? I have an authenticator and run off mac. I haven't had any problems in a while. Can anyone help?

In cases where players have an authenticator on the account and receive the login failed message, this may indicate one of two things – the password is incorrect or the authenticator is out-of-sync.

I would first suggest resetting the password to the account. You can reset the password here:

If you continue to receive the login failed message after resetting the password, you may try resyncing the authenticator. Visit this Knowledge Base article and scroll down to Reset vs. Resync for instructions:
