Aprašymas

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.

What is the client’s Redirect URI?

Most OAuth2 servers will require whitelisting a set 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.

Can I change the client’s Redirect URI?

Some OAuth2 servers do not allow for a client redirect URI to contain a query string. The default URI provided by
this module leverages WordPress’s admin-ajax.php endpoint as an easy way to provide a route that does not include
HTML, but this will naturally involve a query string. Fortunately, this plugin provides a setting that will make use of
an alternate redirect URI that does not include a query string.

On the settings page for this plugin (Dashboard > Settings > OpenID Connect Generic) there is a checkbox for
Alternate Redirect URI. When checked, the plugin will use the Redirect URI
https://example.com/openid-connect-authorize.

I’m using this OpenID Connect Generic Client plugin to integrate WordPress with Microsoft Entra ID (Azure AD), and it works exactly as expected. During my setup I encountered a JWT validation issue related to JWKS handling. I reported it to the developer, and the response was absolutely impressive — the issue was understood, fixed, and resolved in less than 24 hours. This level of responsiveness and professionalism is rare and highly appreciated. The plugin itself is clean, flexible, and perfectly suited for enterprise authentication scenarios. It integrates smoothly with modern identity providers and gives full control over the configuration. Huge thanks to the developer for the fast support and for maintaining such a reliable and well-designed plugin.Highly recommended for anyone needing OpenID Connect / SSO on WordPress.

As simple as it needs to be with no added cruft. Easy to configure and use.

After testing multiple OpenID plugins – even paid one – this is by far the best. Thank you! Some suggestions for improvements: more flexible filtering, better documentation and enhanced multisite support.

Every other plugin is simply a trap to get you paying a premium version. This one simply works as expected, with no bloatware. 🙂

Been trying all other OpenID plugins, ended up uninstalling them, premium issues, bloatware, etc. Tried this once only, now i’m using it on all my Wordpress sites. thanks a lot! I just hope it’s maintained.
