Did what I could to avoid creating ANOTHER account...
Forget about it.
You've got to create another account.
When you go to YouTube, you'll see the following message on the upper right-hand corner of the screen, next to the TubeBuddy icon: TubeBuddy Sign-in Required, Click Here
And guess what...
"TubeBuddy wants to access your Google Account"
"This will allow TubeBuddy to:"
"See, edit, and permanently delete your YouTube videos, ratings, comments and captions"
"Manage your YouTube account"
"Make sure you trust TubeBuddy"
"You may be sharing sensitive info with this site or app. You can always see or remove access in your Google Account."
