Please help: I cannot log into DTube with my Steemit Account... whats wrong?

Hey everyone!

On the DTube login page I typed in my nickname here which is doodlebear and below that this eternally long and automatically generated password for Steemit.

Who do I get that right? Is there another password that I haven't found yet?

In advance, thx for the help!!

(for everyone who helps me: I will upvote all you comments and posts)

UPDATE

Thanks to Hive account@no-far we've got a solution: https://steemit.com/steemit/@musicbox/how-to-dtube-having-problems-login-in-dont-know-how-to-use-it
