I want to take this opportunity to personally thank you and @arcange, for your assistance to @samstonehill in recovering his account. I am proud that I selected you as a witness and @arcange. You are both what I think one part of the witness program is all about, helping and supporting the users during crisis situations such as this and all the hard work you both did during the ddos attack. Thank you for your support of the Steemit community. both of you.

WE need to get 2fa added for added security as well .
Damn the inconvenience. You know what is inconvenient. Losing all your STEEM and loyal followers.

I am not aware of a way 2fa can be implemented at the blockchain level.

If it's possible to have 1 factor authentication, it's possible to have 2 factors. We already have this in a limited form via posting keys vs master keys.

Someone smarter than me will need to explain how it is possible with the blockchain technology. I am not sure how it could be done.
