Greeting everyone,
I would like to post my achievement2 in this newcomers' community after my thorough studies about secuirty on steem blockchain.

Question 1
Have you retrieve all your keys on steemit?
-> Yes, all my keys have been retrieved by using master password on steemit.

Question2
Do you know each of these key functions and restrictions?
-> The functions and restrictions associated with each of these keys are explained as below.
POSTING keys: These keys are used for the daily login which allows us to post, comment, edit, vote and resteem. It also allows to either follow or mute the other accounts depending on your preference.
ACTIVE keys: These keys are meant to be used for transactions like transfer, convert and power up/down. Besides, with the help of these keys, we can vote for witnesses, update the profile and place the market order.
OWNER keys: These keys are used only to recover the account that is compromised. Because it has an ability to change all the other keys of the account including itself.
MEMO keys: These keys allow to encrypt/decrypt memos when making transfers. With no Pound sign before memo, encryption cannot happen.

Question 3
How do you plan to keep your master password?
-> I have saved a offline copy of it in a safe deposit box.

Question 4
Do you know how to transfer your steem token to another steem user account?
->When it comes to the transfer, keep in mind, ACTIVE keys are to be used for signing in.

Go to the steemit wallet, click the drop down box in the steem that displays the total number of steem tokens available.

Click on the Transfer that opens the another page where all the details need to filled up. My username appears by default as a sender and enter the username of another steem user account. Enter the number of steem tokens to be sent. And write the memo. Then, enter Next.

Question 5
Do you know how to power up your STEEM?
->Steem tokens in its liquid form can be powered up. For powering up, log into account with the ACTIVE keys, and go to the steemit wallet. There is a drop down box that shows the amount of steem available. Click it and choose the power up.

Enter the amount of steem tokens that are to be powered up.

A few seconds later, the steem power will be seen increased and the equivalent amount of steem tokens will be shown decreased.
