Hello steemians, My name is Syed Jawad Hossen. Today, I also write about the basic security on steemit as my achievement2 to task. Security means which I also understand about that can secure privacy of my account and no one can access in my account and I also think about that when I also use my account and transfer my balance in others, in that time I also use my keys or password and now no one can give the access in my account and then don't use my account or transfer any balance from my account. It is really safe for which a good initiative from the steemit authority.
