There are about 4 different keys. Are you sure you have the right one?

wait, there are 4 different keys? maybe I don't have the right one. how do I find out my other 3 keys?
Thanks again for replying to me and helping me with this.

Can you find your wallet? After you find your wallet, you can click on the tabs in the wallet to find the passwords, AKA the keys.

thanks for the reply.
Ok, so I have 4 keys, for posting, active, owner and memo; I tried all of them to log into Dtube, and none of them worked. what do I do now?

thanks a lot, you pointed me in the right direction. all I had to do was click "show private key" in my wallet to see the actual key that I log in with.
