To integrate a WordPress membership site with UNACMS for single sign-on (SSO), you need to ensure that both platforms use the same authentication system. Here’s a high-level approach:

1. Choose an SSO Method

You have a few options for implementing SSO between WordPress and UNACMS:

• OAuth 2.0 / OpenID Connect – Use WordPress as an identity provider (IdP) and UNACMS as a client.
• JWT (JSON Web Tokens) – Issue and verify tokens between the two platforms.
• LDAP or SAML – If you have an enterprise setup.
• Custom API-based authentication – Sync user sessions manually.

2. Use an OAuth/OpenID Plugin for WordPress

• Install a plugin like “WP OAuth Server” or “MiniOrange OAuth Server”.
• Set up WordPress as an OAuth provider so UNACMS can authenticate users.
• Create API credentials in WordPress for UNACMS.

3. Configure UNACMS to Use WordPress Authentication

• UNACMS supports third-party authentication via OAuth.
• Configure UNACMS to use WordPress as an OAuth provider.
• Use the OAuth client credentials created in WordPress to allow UNACMS to authenticate users.

4. Synchronize User Data

• Ensure that membership levels, roles, and permissions match between WordPress and UNACMS.
• Use webhooks or API calls to sync user profile changes.

5. Implement Automatic Login & Session Sharing

• Use cookies or session tokens to maintain user authentication across both sites.
• When a user logs into WordPress, redirect them to UNACMS with an authentication token.

6. Test the Integration

• Log in from WordPress and check if UNACMS recognizes the session.
• Log out and verify that both sites end the session.

This is the general methodology of integrating basically any membership site based on the principles of data field mappings and the SSO method.
