Configure Slack 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 miniOrange. By the end of this setup, your users will be able to sign into your Joomla site using their miniOrange credentials, providing a seamless and secure Single Sign-On (SSO) experience.

This integration delegates the authentication process to miniOrange, a robust identity platform. This means you can centralize user management and utilize miniOrange'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.
