2FA authentication is a useful feature, and it's good that Betfury cares about the security of its users' funds. However, it's worth noting that 2FA authentication is not a panacea for account hacking. If a user isn't sufficiently concerned about security, hackers will be able to find a way into their account even with 2FA.
It’s indeed true, hackers always do find means to get the job done even with 2FA in place. That’s where, many sites that use 2FA today no longer prefer the email options to it. Many uses Google authenticator app given that, emails are easily hacked...
With the Google Authenticator app, hackers will be stuck trying to hack your account if they are bold enough to continue in their attempt after seeing that 2FA is in place and expecting that the OTP will be sent to the email of their victim.
