       Tell HN: A stranger is using my YouTube account and Google can't
       log them out
        
       Hi HN,  I believe Google has a grave authentication issue and I
       cannot burst the impenetrable tier-1 support wall to solve it.
       Hopefully I'm wrong, but for the life of me and the support reps I
       talked to, we cannot get a stranger logged out of my YouTube
       account.  The stranger is using my YouTube account through my old
       Smart TV that I gave away (my bad for not logging out, but there
       should be recourse for this).  Once I discovered this, I have
       changed passwords and revoked auth tokens on all relevant services
       (Spotify, Disney+, etc.). All services no longer show the stranger
       accessing them - with the exception of YouTube.  The actions I've
       taken multiple times (as instructed by Google support): - Changed
       my Google account's password - Revoked all "devices I trust" under
       my 2FA settings - Logged out of all devices in the "Your Devices"
       list  This did force me to log back in on my own devices (phone,
       TV), but I still see new videos that the stranger watched in my
       YouTube history. This has been happening for weeks.  Google support
       walked me through these steps and then gave generic "make sure your
       password are strong" article links, but of course, refuse to
       escalate this.  If you wish, you can view the support transcripts
       here (I admittedly got a little short during the 2nd conversation,
       which I regret): https://pastebin.com/GypwBPFj  ---  Some details:
       - The videos in my view history are in Arabic, so I know it's the
       stranger who watches them  - I know the stranger has access through
       my old TV because I saw their activity on all apps I had installed
       on my TV, and I saw my old TV signed in from a distant city under
       "Your Devices" list

       | https://bughunters.google.com/ . This is a significant security

       | existence of an API somewhere which the TV has used, which can
       | create revocation-resistant keys.

       | In Google's _OAuth 2.0 for TV and Limited-Input Device
       | Applications_ page,
       | https://developers.google.com/identity/protocols/oauth2/limi...,
       | it says:
       | 
       | "Note that there are limits on the number of refresh tokens that
       | will be issued; one limit per client/user combination, and
       | another per user across all clients. You should save refresh
       | tokens in long-term storage and continue to use them as long as
       | they remain valid. If your application requests too many refresh
       | tokens, it may run into these limits, in which case older refresh
       | tokens will stop working."
       | 
       | Maybe you could try issuing thousands of OAuth refresh tokens (or
       | more) for your account, in the hope that it will hit some
       | internal limit and automatically revoke the one stored inside
       | that Smart TV?

           | Just curious, what's the line, if not this? Hypothetically of
           | course, I'm okay with it if you're responding with "I'd
