Honestly at this point, I don't even think we'd need to worry about hackers anymore. It's been 8(?) years and I'm pretty sure they'll be long gone. I'm sure there would be other easier ways to deal with hackers?
Hackers don't just hack something and leave. Their goals are to steal as much personal data as possible and cause as much chaos as they can. No game or website can let down their guard these days. Places that do let down their guard end up having more and more security breaches. And for a game that is already experiencing a dry season as far as player activity, another hack would be even more destructive. When it comes to player safety and security, there cannot be compromise. Not everything the community wants is safe and secure enough. And if something gets hacked, who would be held responsible for not securing things properly? That's right. Raz and the FH staff would be liable for it if proper security had not been in place.
Technically, the login page is FeralHeart's form of 2FA (2-factor authentication). And a lot of games and websites are using similar methods these days. Perhaps the 2FA method used by FH could be changed to a different method, but it probably isn't going to be removed entirely.
