Steem 2FA implementation

As steem becomes more and more popular and many users holding bigger amounts of steem
in their accounts, criminal potential grows along.
Security should have no.1 priority.

If you are interested in 2FA as well, please share the post, so the devs may consider implementing it soon.
If it´s a question of cost, I´m shure the community is willing to donate some steem to make it happen.
