In addition to this, Poloniex should provide the 2FA auth-key while setting it up, so users can recover their 2FA in cases like this. So many other sites do this.
Yes please, this would be great.
BTW, I'm the guy that can't get them to reset 2FA on my account even though I've signed messages.
Poloniex: are you reading this thread? I'd really like you to reassign my ticket to someone who knows how to verify signed messages.
