Authentication method mismatch during account registration
OpenAI Developer Community

Hey @DevDash! That login flow sounds stuck in a weird loop.
Please try this from an incognito/private window: go to chatgpt.com, type your email in the Email address field, then click Continue. Don’t start with “Continue with Google/Apple/phone.” If your organization uses SSO, you should continue through the SSO flow after that.
You can also check out the article @LarisaHaster shared for more clarification: Authentication Troubleshooting FAQ
Using incognito should help clear out any existing sign-in cookies that might be forcing the wrong login method. If it still doesn’t work, support@openai.com would be the best next step. If you already reached out, feel free to share the case ID here and I can take a closer look.
