Is there any possibility of setting up two-factor authentication (2FA) for Stack Exchange OpenID authentication?
I could just use my (already 2FA-enabled) Google account for Stack Exchange, but I would prefer to continue use Stack Exchange OpenID.
After Heartbleed (which, I appreciate, didn't affect Stack Exchange, as you use IIS and Schannel, not OpenSSL), there have been a lot of recommendations to change passwords and to enable 2FA where possible.
So, what are the chances of a text-messaging-based or Google-Authenticator-based 2FA for Stack Exchange?
