Configure Auth0 Single Sign-On (SSO) with Joomla OAuth Client Plugin
Overview
Single Sign-On (SSO) with Auth0 in Joomla uses OAuth Authorization to provide users secure access to the Joomla
site. With our Joomla OAuth Single Sign-On (SSO) plugin, Auth0 acts as the OAuth provider, ensuring secure login for
Joomla websites.
The integration of Joomla and Auth0 simplifies and secures the login process using OAuth protocol. This solution
allows users to access their Joomla sites with Single Sign-On (SSO) using their Auth0 credentials, completely
removing the need to store, remember, and reset multiple passwords.
In addition to offering OAuth Single Sign-On (SSO) using Auth0 credentials, the plugin also provides advanced SSO
features like user profile attribute mapping, role mapping, and Azure multi-tenant login and providing site access
based on organization email domains. For further insights into the array of features we offer within the Joomla
OAuth & OpenID Connect Client plugin, kindly visit our page here. You can
follow the below steps to setup Auth0 OAuth SSO with Joomla.
