Configure Auth0 Single Sign-On (SSO) with Joomla OAuth Client Plugin

Overview

This guide will walk you through configuring our Joomla OAuth Client extension to enable secure login with Auth0. By the end of this setup, your users will be able to sign into your Joomla site using their Auth0 credentials, providing a seamless and secure Single Sign-On (SSO) experience.

This integration delegates the authentication process to Auth0, a robust identity platform. This means you can centralize user management and utilize Auth0's advanced security features directly for your Joomla site. Our extension acts as the bridge, handling the complex OAuth 2.0 protocol behind the scenes.

Configuration Steps

In this configuration, Auth0 functions as the OAuth server, while Joomla allows users to log in with their Auth0 credentials by utilizing the Joomla OAuth Client Plugin.

Step 2: Configure Auth0 as OAuth Server

• Go to your Auth0 Dashboard.
• Go to Applications tab in the left panel and then click on Applications.

• Now click on the CREATE APPLICATION button.

• Select Regular Web Applications and click on Create button.

• Now go to Settings tab.

• Scroll down to Applications URI's section and enter the callback url we copied in Step 1.

• Then scroll down and then click on Save Changes button.

Step 3: Configure Client ID & Secret

• Copy the Client ID and Client Secret from Basic Information section in settings tab.

• Now go to Users tab under User Management from the left panel.

• Click on Create User to create a new user.

• Enter all the required details and click on Create.

• Go back to your Joomla Dashboard. Then go to Step 2 in the Configure OAuth tab.
