OAuth2 Server Plugin for Moodle

This plugin enables your Moodle site to act as an OAuth2 authorization server (OAuth2), allowing external applications to authenticate users using their Moodle credentials.

It supports the OAuth2 Authorization Code flow, making it useful for integrating Moodle-based identity verification into custom systems such as applications, portals, custom AI agents, or third-party services. Note that while it allows credential delegation, it is not a full Single Sign-On (SSO) solution by default.

Key Features:

• Acts as a compliant OAuth2 Authorization Server.
• Supports the Authorization Code Grant flow.
• Allows external systems to obtain access tokens and refresh tokens using Moodle credentials.
• Built using bshaffer/oauth2-server-php as the underlying OAuth2 library.
