Hello STEEMIT am actually happy to be writing my second achievement today on Basic security.
I want to use this mean to tell everyone what i understand when we talk about basic security in STEEMIT

BASIC SECURITY KEYS
In STEEMIT we have four main keys which are:
1.Posting key
2.Active key
3.Owners key
4.Memo key

1. POSTING KEY - With the posting key, users can post, remark, edit, vote, resteem, follow, or silence other users' accounts. The majority of users ought to be using the posting key to sign in to Steemit daily. A limited posting key exists to minimize the harm that a compromised account key would be able to do because the more you use your password or key, the more probable it is to be compromised.

2. ACTIVE KEY - The active key is intended for more delicate operations including money transfers, power up/down transactions, Steem Dollar conversions, witness voting, altering profile and avatar information, and making market orders.

3. OWNER KEY - Only when absolutely required should you use the owner key. Its ability to alter any key associated with an account, including the owner key, makes it the most potent key. It should only be used to restore a compromised account and should be kept offline.

4.MEMO KEY - When transferring money, this key is used to encrypt and decrypt memos. Use the pound/# sign before a note to encrypt it.

If you forget your owner key or password, there is no way to restore your account! It is crucial that you preserve your master password in a secure location where you won't lose it because your account is valuable.

Is advisable for us to keep an offline duplicate of our password in a secure location in case our hard disk fails or we might experience other disasters.

DIFFERENCE BETWEEN OWNER KEY AND MASTER PASSWORD
All additional keys, including the Owner Key, are created using the Master Password. The only time your Master Password should ever be used is when you are trying to recover your account; in this situation, you should get the Master Password from your secure storage.
You receive a password when you register, which is the Master Password. Then, using that password, go to your wallet on Steemit.com and get all the other keys.

Now to answer the 5 question below in respect to my password.

1- Have you retrieve all your keys on STEEMIT?
_ Yes i have them all.

2- Do you know each of this keys function and restrictions?
_ Definitely as stated above.

3- Do you know how to transfer your steem token to another user?
_Yes.

Log onto your Steem wallet and hit the little dropdown menu right next to your STEEM balance:

Now, hit the option "Transfer" and type in the user name you want to transfer your funds to:

and hit the transfer button
4- how do you plan to keep your master password?
_ I actually prepared a folder for it in flash drive.

5.Do you know how to power up your steem?
_Yes.
Powering up your STEEM and converting it to STEEM POWER will help you increase your influence on this platform. Not only will your votes have more power and mean higher rewards the more SP you possess, you'll also earn a small amount of interest on your held SP.
Just hit the small dropdown menu right next to your STEEM balance and hit "Power Up

and then you will see a page like this

then put the amount wich you want to convert into steam power and hit the powerup and this done.

I am sure with this stated above i definitely understand a lot on STEEMIT BASIC SECURITY
