I'm not in other countries so this is a genuine question - does using a Google or Microsoft login not obviate that need?
You get redirected to enter your name and phone. Did it not ask you?
edit: You can't even access parts of openai sites from the "naughty" countries.
they are probably banned from doing any business in eg. Russia
I'm from Egypt and banned.
I'll save you from my diatribe about the pitfalls of you-as-a-user of using Google or Microsoft for login. But because of that, I don't know and so can only guess at what level OpenAI choses to rely on Google/Microsoft to validate accounts.
