What problem does it solve?

Implement centralized OAuth 2.1 / OIDC authentication using Better Auth with MCP assistance for guided configuration and rollout across multiple apps.

Core Features & Use Cases

  • MCP Server Setup: Configure and manage a Better Auth MCP server with guided, repeatable steps.
  • SSO Client Integration: Set up Next.js apps as SSO clients with PKCE and JWKS-based token verification.
  • Token & JWKS Management: Establish secure token handling patterns and JWKS verification for offline validation.

Quick Start

Run the MCP-based setup command to scaffold Better Auth and apply the generated settings to your authentication server and Next.js apps.

FAQPage Schema
How do I set up centralized OAuth 2.1 authentication with Better Auth across multiple Next.js apps?▼

You can establish centralized OAuth 2.1 authentication by running the MCP-based setup command to scaffold the Better Auth server and apply generated SSO client settings across your Next.js applications.

How does PKCE flow integration work when using Better Auth for SSO?▼

PKCE flow integration in Better Auth secures SSO client connections by requiring a code verifier and challenge during the OAuth 2.1 authorization process, preventing token interception attacks.

Can I use Better Auth for JWKS-based offline token verification?▼

Yes, Better Auth supports JWKS-based offline token verification, allowing your Next.js SSO clients to securely validate OAuth 2.1 ID and access tokens without querying the auth server per request.

Do I need a dedicated auth server to deploy Better Auth OIDC and SSO clients?▼

Yes, deploying Better Auth OIDC requires a dedicated server configuration scaffold to act as the central authority, while your Next.js apps function as SSO clients connecting to it.

What is the best way to manage token handling patterns and JWKS in a Better Auth environment?▼

The best way to manage token handling and JWKS in Better Auth is using the MCP guided setup, which establishes secure token patterns and configures JWKS verification for offline validation.
