TL;DR, one SSO failure diagnosed, won’t be fixed, refund for me 
thank you, but data is trapped. Support does work but slowly.
In my case, this “Something went wrong while getting your SSO info” failure was caused by having $ in my email address. RFC2822 compliant, but unacceptable to this software. It took me a while to discover this as the cause, plus a grumbling session with another LLM, and then a flash of inspiration.
You can test this by attempting to log in as foo$bar@example.org = fail. No password will be requested, it doesn’t get that far. Support currently does not plan to fix this bug.
The history of it, as I recently found out from Support, is that it would not have been allowed to happen if I had registered more recently… but I made my account a long time ago and software changed since.
The workaround of switching from auth.openai.com to auth0.openai.com stopped working after/around 2024-10 so once my login cookie expired I was locked out.
Support advised that I tell the credit card to stop payments. They also kindly offered refunds for several months, where it is provable that I could not have used the system. Yes I failed to chase it up when the problem became clear… the world had me busy at the time.
The chat history and Memories in my account are going to be trapped, and possibly I can’t even get them exported or deleted? I haven’t pressed for that.
This login @Sprazzle is also tied to that id, but the login cookie for the forum persists… I guess I should ditch it and make another.
It took about a week in the web chat to get to this point, and I met five names after ‘Fin’ the auto-greeter bot. At times the responses are infuriating because the reader of my message seems not to understand that I’ve already diagnosed the problem - whether this is the old tech support problem “I have to follow the script before I can escalate to the next level of support technician” or something else is open to speculation. “Are all OpenAI support avenues just run by AI?”
Best advice if you’re stuck with support is to answer each point in turn, keep each file you upload in case it gets lost / falls off the webchat again, keep the window open, and be very patient.
Overall I’m fairly happy with the outcome 
because and I learned two new debug tools, How to Create HAR File from Google Chrome, Firefox, and Analyze it? (first ddg hit - not sure about quality) and https://har-sanitizer.pages.dev/ (untested).
