I made a post asking developers and witnesses to see what they can do regarding steemit security.

According to their answers I don't think we will be seeing any upgrade on security and I don't think they can put any additional security measures like 2FA , sms or email verification.

However, there is a reply from @gtg and @dan about how to make sure our account is safe.
