1
Turn on Developer Mode
In ChatGPT, go to Settings → Apps and turn on Developer Mode.
2
Create the app
Create a new app with OAuth authentication and this URL:ChatGPT finds the sign-in settings on its own, so you don’t need a client ID or secret.
3
Turn off OpenID Connect
Expand Advanced Settings and uncheck OIDC enabled. If you leave it on, sign-in fails.
