Connect the first and second accounts
Open ChatGPT Settings and select Apps or Plugins, depending on the interface shown for your plan. Choose the relevant Google connection, review the account already connected, then select Connect another account when that option appears and complete Google's authorization flow.
OpenAI says the feature supports Gmail, Google Calendar and Google Contacts on eligible Plus, Pro, Business and Enterprise plans. Availability can still depend on region, device and workspace administrator policy.
Reduce the permission surface
During authorization, inspect the requested services and choose fewer Google apps when the interface allows it. A calendar-planning task does not automatically need email or contacts, and a personal account should not be connected merely because it is signed into the browser.
For managed workspaces, administrator approval and Google Workspace controls may still apply. Connecting an account does not expand the files, messages or calendars that account is already permitted to access.
Make account selection explicit
In the request, identify the account by purpose rather than pasting a full address into every prompt: for example, ask to compare the work calendar with the personal calendar for a named date. Check that cited messages or events came from the expected account before sending, scheduling or summarizing sensitive information.
Test with a harmless event or email that exists in only one account. If the answer is ambiguous, ask ChatGPT to state which connected account supplied each item instead of assuming the merge was correct.
Review and disconnect
Return to the app's Connected accounts or Connection section to review account-specific settings. Remove an account when the project ends, a device changes hands or the connection is no longer required.
