EDIT: Worked it out. It's just a steemconnect thing worded badly on dtube's part. Thanks though.

Do you know if this is the right thing to do? I'm having trouble working out where I'm supposed to post the key so I searched Steemit for pretty much that whole phrase @aellly posted and this came up. I thought it was in the profile editing section or something but I couldn't see anywhere there to put keys for other applications like dtube. I already have a dtube account from earlier but I'm just trying to claim it and I'm not sure how.
