Have you recovered all your keys on Steemit? Next, the Time I registered on steemit.com and sign up, I download a file in PDF format to my computer. I open the file and read it very Attentively. Later, I understand that this is a very important file. And that if it is lost, I will not be able to do any work on my Steemit account. ![shahinrezakey.png](https://cdn.steemitimages.com/DQmZFoWBeCumkZagLuP5wZLtaEQAkcG1SsMZJouMYAnWuzV/shahinrezakey.png) Five types of security are found in this file.

Do you know each of these key functions and limitations? Yes, Every key has its respective functions and we will see them in their special paragraphs. Posting key: Account users are allowed to vote, comment on, and post to other accounts. You should log into Steemit using an account with a posting key. ![posting key.png](https://cdn.steemitimages.com/DQmWBrdCS6PvyRMP5XNG8ftfTwn5y6EWpmZRiooTAYcMpnH/posting%20key.png) Active Key: This activation key permits you to enable witnesses to vote on transactions, transfer funds, and convert Steem Dollars.

Because it can alter any account key, it is trusted that this is true. This key is used only in cases where it is absolutely necessary. This key is used to recover accounts. The owner key is used to change the post key and active key. ![1111.png](https://cdn.steemitimages.com/DQme358Now3epPsqzd35tYWDGt7Px7Faau3cRuwjAxvVoD3/1111.png) Memo Key: It is used to decrypt or encrypt memos during funds transfers.

You were given a master key when you signed up. You should keep this master key safe. so as not to be deleted in any way. Because once it is deleted it cannot be recovered. You will not be issued a new master key. Allows access to all keys in your wallet. So store master keys very carefully My master password has been kept very safely in various secure locations which include:  Written down in my journal.  The Pdf file with all my keys is stored on a USB Pen drive.  Screenshots are stored in my Google Drive.

Then the power-up feature permits me to create my power on Steemit. I want to see my wallet in order to power up. I have done this previously too. The button to power up is located in the drop-down menu. The power-up icon will be displayed. You'll then be taken to various pages. ![power up.png](https://cdn.steemitimages.com/DQmbD7f29XwZVTHFMka7F1hheqNVjNh8KviqXBPCYm7zX1M/power%20up.png) After then, I complete the amount box and hit power up. Next, I get a confirmation message. Next clicking OK, I confirm and am presented with a completely new page. Here, I can enter my Active key to complete the process. Today, I mentioned Achievement-2 and wished everyone involved with Steemit a bright future. Thanks for all Md.
