owner: main key that controls everything and can change all keys including owner key.

Thank you. Is the owner key also used for mining?
I don't know which keys are needed to mine in an existing account, although it probably includes the signing key which isn't listed there but is yet another key that is part of the witness data attached to an account. When you mine without having already created an account you just give one WIF key and it is inserted in all the slots when the account is created.
What and where is the WIF key ????
i also cant find it :(
The miner uses your Private ACTIVE key for mining, according to "A Quick Guide on How to Mine Steem on Windows"
– If you are not sure where to get the private key, then just login to your steemit.com account, go to your Profile and then to the Permissions tab. Here you need to click on Show the private key for Active (you may need to relogin first). Do note that the key shown by default is the public key, you need to show the private key and use the private key in the config! Alternatively you can use the Owner private key, this is also your login password, but due to security reasons you better stick with the Active key.
