But even doing all this, if bitcointalk forum gets somehow compromised or hacked again (happened before) someone can steal even our hardest passwords.
Can we expect to see some solutions for this issue in new forum software?
Maybe using 2FA, OTP or something else?
The previous hack on accounts was due to an SMF vulnerability exploited through the security question option, it has been disabled since then.
2FA has been suggested many times on the forum, but there has been no action taken regarding that, for now you could use it on accounts linked to your profile, such as your email address to prevent a breach. Also keep your email address safe and do not share important links, such as your captcha bypass link.
