SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill guides implementing OAuth 2.1 / OpenID Connect authentication using the Better Auth platform with the OIDC Provider plugin. It helps you centralize authentication, enable Single Sign-On across apps, and configure an extensible authorization server.

Core Features & Use Cases

Auth Server Setup with PKCE: Create a public OAuth2 client and secure authorization flows for SPAs.
OIDC Provider Integration: Extend userinfo with custom claims and admin dashboards for user management.
Admin-Controlled Client Registration: Gate client registrations behind admin access to prevent uncontrolled clients.
Use Case: If you have many microfrontends or SaaS tenants, you can unify authentication under a single identity provider and reuse policies.

Quick Start

Run the setup to configure a public client with PKCE and enable a basic OIDC provider for a SPA at http://localhost:3000.
