On September 24, OpenAI added new External access controls to the administration console for ChatGPT Enterprise organizations. The update is in Admin Preview, and both new permissions are disabled by default.
The Connectors permission lets an administrator allow ChatGPT Sites to request access to each visitor's connected apps. The Ads permission lets an external app request access to ChatGPT Ads. Even after organizational approval, users still need to complete authorization using their own account permissions.
OpenAI emphasizes that Identity sign-in identifies users but does not grant access to Connectors or Ads data. This specific update is documented for ChatGPT Enterprise, not as a general launch for Business or Edu.
