After the registration, I follow the steps and download the keys and print it out. I also save it in my cloud drive. This is the second post which is about the security measures in steemit. I hope my understanding about this will be accurate.I start getting to know the security keys. Here is my understanding about each keys.
private Posting Key:
comments and votes to these posts. If users feel interested in one particular user, they can follow it with this account.
This one is for basic functions in steemit and it does not allow other functions which contain secure content to work. It is commonly used for login as users mainly view the posts of other users and post blogs, edit posts and comments, resteems.
If you don’t want to do any interactions with some users, you can use it to ignore these users by muting it without disclosing any personal information.

Private Memo Key:
When the user wants to transfer funds to another user attaching a memo inside this transfer and not let others to view the memo content, this memo key is used by adding the # sign in front of it in the memo textbox. Private Active Key:

When you have to deal with cryptocurrency transactions like fund transfer among steemit, steemit power and steemit dollar and savings, make steemit power/down in the steemit wallet, buying and selling steem dollars
Private Owner Key:
This key is for emergency use of recovering any key of the user account so it must be stored offline in a secure medium. Master Password:
This key is to obtain all keys above in the Steemit account. It must be kept safe to avoid being stolen and losing the Steemit tokens.

This device must be kept in a place not easily seen. Moreover, I print the password file and store it in a place that is also not easily seen. Besides keeping the passwords in the cloud device, I keep these keys offline by storing the password file in the external storage device with password protected and encrypted. Transferring the Steemit token to another Steemit account.

First in the wallet, choose Transfer by clicking on the dropdown list beside the steem token section.

First, you choose Power Up in the dropdown list beside the steem token section.
Then fill in the amount in the popup and click Power Up.
