I hope you all are good and you have enjoyed the day very well. Now i am here to complete my achievement 2 that about the basic security of steemit. So without ny delay I will start

Have you retrieve all your keys

Yes ! I retrieve all my keys and I put them offline in a usb folder. I did not prefer to keep the password and keys in google drive online because in this way your data is always at risk due to hacking system.so that is keep them in laptop in a separate folder.

Function and restrictions of all the keys

Active key
When we have to transfer token, power up or power down the account, have to convert SBD, certain profile changes,for placing an order,to publish the witness,For all above work we use Active key.
Posting key
Posting key is used to post or comment, to edit a comment,to mute account, to follow people and to Resteem content.
Owner key
If we want to decline voting rights, to make some other person owner of the account, to change active key or posting key, to recover our account , in all above cases we use owner key.
Memo key
This key is not of so much importance, we can also ignore this, this is mostly used to read encrypted message and to send encrypted message.
Master password
When I made my account, there was a master password was shown. I copied that password and save it, then I paste it in next tab to get all keys in pdf form
