This plugin integrates the OpenID standard into a content management system, allowing site owners to implement decentralized authentication. It is designed for administrators who want to simplify the login process for their users and enhance security by reducing reliance on site-specific passwords.

• Accept External Identities: Users can sign in or post comments using their existing OpenID credentials from other providers, eliminating the need to create a new account.
• Issue Site-Specific Identities: The site can also function as an OpenID provider, allowing users to use their identity from this site to log into other supporting services.
• Centralized Authentication: Manages user authentication and commenter verification through a single, established protocol, potentially improving security by removing the need to store and manage local passwords.
• Requires Complementary Plugin: For full functionality as a provider, the plugin requires an additional extension (XRDS-Simple) to properly publish the necessary service discovery documents.

Important Note: As of March 2024, this specific plugin version has been closed on its original repository due to a security issue and is no longer available for download. This overview describes its intended functionality for informational purposes.
