Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Of course, there are some folks that do have the code and you'd have less hassle doing that if you don't already have a GMG account, but I figured it's better to let you know it's on sale.
I'd be careful about using a 3rd party site to get a code.
Steam in particular shut down a lot of the 3rd party codes last year (and a few other times) saying they were not legit.
A lot of people playing The Secret World lost access to the game till they paid for another copy. I forget what other games were affected as TSW was the only one I was playing at the time.
