This is exactly the kind of failure Google is notorious for. Google has put me through their login purgatory multiple times where the only solution was to wait many days and try the same steps again until it works. I think it would be much easier to get this resolved with OpenAI than with Google.

I'm not trying to defend Google (shudder!), just trying to be helpful:

- Enabling 2fa in my accounts has solved this problem for me

- I hear that hardware security tokens are even better to get Google to not worry that you're an imposter, but I haven't done that myself
