<p>Well, different keys have different functions.</p>
<p>E.g. posting keys for posting and voting on the blockchain, active keys to make transfer, owner keys to validate ownership and memo keys to facilitate memo sending and reading.</p>
<p>It's actually a great idea because there would not be a single key to control all functionalities. As such, in cases where the keys are compromised, let's say the posting keys, you would still be able to gain access to your Steemit account!</p>
<p>The keys actually have their functions! So, better know them well and always choose to reveal the necessary keys only!</p>

<p>Because it is integrated with blockchain, making all systems safer, keep away from hackers, because it is encrypted.</p>

<p>each keys on steemit has their own functions,i believe all these keys is just a good way to secure your account and make it very difficult for anyone to steal money from your steemit wallet,though some users could find it incovenient to be entering different keys whenever they want to use some certain features on steemit,but i believe that it is bettee to be a bit inconvenient than to loose all the money in your steem wallet....</p>
