OpenID Connect Generic Client

A simple client that provides SSO or opt-in authentication against a generic OAuth2 Server implementation.


This plugin allows to authenticate users against OpenID Connect OAuth2 API with Authorization Code Flow. Once installed, it can be configured to automatically authenticate users (SSO), or provide a "Login with OpenID Connect" button on the login form. After consent has been obtained, an existing user is automatically logged into WordPress, while new users are created in WordPress database.

Much of the documentation can be found on the Settings > OpenID Connect Generic dashboard page.

Frequently Asked Questions

What is the client's Redirect URI?

Most OAuth2 servers should require a whitelist of redirect URIs for security purposes. The Redirect URI provided by this client is like so: https://example.com/wp-admin/admin-ajax.php?action=openid-connect-authorize

Replace example.com with your domain name and path to WordPress.
