Signing into ChatGPT with SSO for Catholic Archdiocese of Sydney

Overview

Staff must sign in to ChatGPT using the organisation login flow, which ensures they are placed into the Catholic Archdiocese of Sydney (CAS) workspace.
This login method is required until SSO is fully enforced and AI tools are rolled out across the Archdiocese.

How to Sign In

1. Go to the Login Page

Navigate to:
👉 https://chat.openai.com
or
👉 https://chatgpt.com

2. Enter your CAS email address

On the “Log in or sign up” screen:

1. Scroll to the bottom section showing:
   OR → Enter your email

2. Type your CAS email:
   firstname.lastname@sydneycatholic.org

3. Click Continue

This step is required for ChatGPT to detect that your email belongs to the Catholic Archdiocese of Sydney.

3. Select “Catholic Archdiocese of Sydney”

After entering your email, a new screen will appear showing:

🔐 Catholic Archdiocese of Sydney
— This is your organisation login button.

Click this option.

Do NOT choose:

• Continue with Google

• Continue with Microsoft

• Continue with Apple

• Continue with phone
  These will create or redirect you to a personal workspace.

4. Complete the Entra SSO Login

You will now be redirected automatically to the Microsoft Entra ID sign-in page:

• Confirm your CAS email

• Enter your password

• Approve MFA if required

After successful authentication, ChatGPT will return you to the app and place you in the correct workspace.

Confirm You Are in the CAS Workspace

After signing in:

1. Click your profile icon (top-right)

2. Check the workspace name:

🏢 Catholic Archdiocese of Sydney

If you see “Personal Workspace” or something else:

• Click Switch workspace

• Select Catholic Archdiocese of Sydney

Why This Login Path Is Required

Using your email-first login ensures:

• ChatGPT recognises you as a CAS staff member

• Your account is placed in the CAS business workspace

• Security policies and access controls apply correctly

• No personal or unmanaged ChatGPT accounts are created with CAS emails

Later, once SSO enforcement is enabled in Entra ID, this process will become automatic.
