I have realize the importance of this and I am aware of it more than ever .Thats when I tried to create my account a couple of months ago. I didn't know much about it and I tried to create an account .After completing all the procedures I had created the account but at that time I did not understand the importance of master password was too long and I didn't save it anywhere and copied it put it in a draft of a message and I closed that tab in my mobile by mistake so the password was gone .So that's why that account was lost but now I will not repeat this mistake and have saved and have noted /written all these important passwords somewhere secure

Now through this achievement, I have already studied each key and known their respective uses.at first, I thought there was only one password and that would work everywhere. now I have come to know that there are five passwords/keys and every one of them has their own purpose.

Master key:

This is the most important key losing this key means losing your account simply.

Posting key:

with this key you are able to vote comment post and follow accounts.

Master key:

This is the second most important key after master key.with this key you can completely gain control over an account.With the Owner Key you can transfer any funds in your Account, Vote for Steem Witnesses, and granted full permission to change all keys, this includes the Owner Key itself.

Memo key:

the memo key is used for private messaging.for encrypting and decrypting private messages whn transferring funds.

Active key:

This key is important to and i used for transferring funds, power up/down transactions, converting Steem Dollars etc.

I know that we should write them and have written them in my diary and have putted it somewhere save.

HOW TO TRANSFER STEEM TOKENS TO OTHER ACCOUNTS AND HOW TO POWER UP

Memo key is required for this transaction.then click on wallet to open wallet page as stated in picture click on arrow and select tranfer from dropdown menu.fill the form with information and afer that memo key will be required and you have sucessfuly made transaction.
