Nice additional security feature now everyone is curious how to hack the mail address provided then if 2fa is installed on email another work.
Hmm, why would you want to hack the email though? I don't think the 2fa code is stored in the email, though I do see that point of using the email to create a support ticket saying that it the owner lost the 2fa keys. Problem is I don't think this is part of the hack bounty of BitDice or any other site for that matter as if you are able to hack the email then that means the one that is unsecure is the email and no longer the site.
