Blizzard Authenthicator Code while trying to connect

[Ouragen]

Hi all , im trying to connect to Medivh , to create a character but when i log in , a pop up appears and it said "enter the blizzard authenthicator code".

I DL the wow tbc version of warmane with the realmlist already done , i checked it and its written :
"set realmlist logon.warmane.com
set patchlist "

So its good i dont know if its due to DDos attack or anything else? Please help. Thanks

Click on "My Account" at the top of the page (note that you must currently be logged in).
Go to "Security".
Here, you can set your authentication type for your website account, the game, or both.
It's recommended that you use one of the two authentication methods. If you don't have a smart phone or tablet to use the Google authentication method, then you can still use the email authentication method if you wish.

If this is currently disabled entirely, then I'm honestly not quite sure why you're being prompted. A DDoS attack shouldn't really have any bearing on this.
