Awesome tip. I have a runescape account now, but at least I am able to use youtube premium!Remember, none of this has to do with the site in question - just finding a site that has the "sign in with Google" option. Once you sign-in, if you don't have an account, you can abort the sign-up process and you'll still be signed-in to Google (thus YouTube). So even if you don't have a Plex, TMC, or Dropbox account, you can -- er, used to be able to -- use those sites' sign-in page to sign-in to Google. It's actually signing-in to Google (you're not giving your account to TMC or Plex or whatever), but it used a method that Google still allowed to be done this way.
It's convoluted, complicated, senseless tech-company logic that, honestly, is probably trying to fight-back against companies that are doing authentication the wrong & lazy way (I worked for a company that implemented the wrong & lazy way for Google sign-in in their app - looked like a phishing page in an embedded browser!), and that's solving a bigger problem while creating "smaller problems" (us) along the way. So it's a greater good thing, but creating frustrating problems like this in the process. Forcing companies to implement Google sign-in the correct way is nice.
When this is "fixed", 100% certain the YouTube sign-in will be natural and as-intended - just signing in through the YT site itself, or maybe through another straightforward technique... but now that it's completely broken, Tesla has no choice but to give it the five minutes of attention it needs to be fixed. That's nice.
As a small aside, there was another reply in my Reddit thread saying that yes, Dropbox login is now broken as well, but NOW TRY RUNESCAPE No, really, that's the advice... head over to runescape.com, go to "full site", and hit "log in" in the upper-right corner. Maybe THAT Google login is different? This is getting intense, man... seems likely that we're going to be chasing down "legacy" apps that still somehow have this mechanism enabled.
Does that work for anyone?
You don't have to sign up for Runescape at all - at least, from what I can tell. You should only have to get *up* to that point where it asks if you want to allow, then just ignore the message and browse, say, to Gmail or something. It should show you as logged-in, and thus you'll also be logged-in in YouTube.RuneScape worked fine just make sure during the signup you click on the "Allow" blue button at the end, otherwise it won't work. Happy YouTubing and btw YT Music also works great pulling in your playlists and history FTW
