    anyone can create an email address and sign up
    including my teen kid

    my password is like 20 long and random generated
    so I have no chance of remembering it.

Solution: Ask your kid to set up a throwaway account for you. With an easy to remember password.

That does not address the tracking I have a problem with so not exactly a solution. Every time I use that throw away account on any pc I become connected forever to that pc in many data points. Youtube is getting plenty of data even if I use a throw away account. I would need to make a new throw away account, from a different ip address each time I wanted to do as you describe to avoid tracking so sometimes I just don't bother with the video.
