SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Implement OAuth 2.1 / OIDC authentication using Better Auth with MCP assistance. Use when setting up a centralized auth server (SSO provider), implementing SSO clients in Next.js apps, configuring PKCE flows, or managing tokens with JWKS verification. NOT when using simple session-only auth without OAuth/OIDC requirements.

Core Features & Use Cases

  • Centralized auth server setup with guided MCP-assisted configuration for PKCE, JWKS, email verification, and admin dashboards.
  • SSO client integration in Next.js apps with PKCE for public clients and secure token storage via httpOnly cookies.
  • Token lifecycle management, JWKS-based verification, client registration, and multi-app SSO workflows.

Quick Start

Follow this instruction to begin configuring Better Auth-based OAuth2/OIDC SSO for your multi-app platform.

Frequently Asked Questions about configuring-better-auth

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up a centralized OAuth 2.1 SSO server using Better Auth?▼

Implementing SSO clients in Next.js with Better Auth requires configuring PKCE flows for public clients and securing token storage via httpOnly cookies. This approach ensures safe token lifecycle management and JWKS-based verification across your applications.

What is the role of JWKS verification in OIDC authentication with Better Auth?▼

JWKS verification in OIDC validates token signatures against public keys. Better Auth uses JWKS configuration to ensure secure token lifecycle management and centralized verification for multi-app SSO integrations.

Do I need PKCE when configuring OAuth 2.1 public clients in Next.js?▼

Yes, PKCE is required for OAuth 2.1 public clients. Better Auth implements PKCE flows to secure authorization code exchanges, preventing token interception when integrating SSO clients in Next.js applications.

When should I avoid using Better Auth for OAuth and OIDC configuration?▼

Avoid Better Auth for OAuth and OIDC configuration if your application only requires simple session-only authentication. It is specifically designed for centralized SSO setups needing PKCE, JWKS verification, and multi-app token management.
