Hey I have not seen it mentioned here yet, BUT..> FINALLY!!!!
It's great to finally have 2FA in bitcointalk but better read what theymos said... if your email address is compromised attackers can bypass and disable 2FA in your forum account.
Better make sure you have good protection for email that is connected with bitcointalk, maybe with additional 2FA.
If you use the forgotten-password function, then there's an option to remove the 2FA. So 2FA does not provide any protection in case of a compromised email.
