Google Authenticator Stopped Working
It memorizes your IP and there for you are listed as a known account user. It pops up when someone who does not have a known IP trys to log onto your account.

I believe that this is working as intended, so that you are not required to input a code each and every time you log in from your normal location (i.e., home). I talked to our Security Team about this a few weeks ago and I believe that in the final version of the Authenticator, you will be given the option to require the inputting of a code each time. That option isn’t available now, but as I said, I believe it may become available when the Authenticator moves out of beta.

Ok I think it is working that way, as I just used my laptop at work to check this thread and had to input a code. It is nice to know it is working. It was just weird seeing it at login for a few days and then it was gone. Thanks for checking up on it, feel free to close down the thread now. Keep up the great work on the game I am loving every minute.
Meithar it sounds like you clicked Remember my network hence it didn’t require you to re-input the auth key code.
I suggest you contact support to remove any saved Network IP’s. I am concerned about this option myself. with the recent raise in GW2 account hijacks this is just one option that personally should be disabled although the chances of a hijacker being in the same IP range as you if they was they will also not need to verify the account.
Hope this helps!
