SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you implement secure, framework-agnostic authentication in TypeScript so you can avoid reinventing login, sessions, and security-critical flows.

Core Features & Use Cases

  • Email/password authentication for signup and login with session-based protection.
  • OAuth social login (e.g., GitHub) to let users authenticate with existing accounts.
  • Advanced auth options including 2FA/MFA and passkeys/WebAuthn, plus multi-tenant organization support.
  • Use Case: Build an app where users can sign in with email or GitHub, optionally enable 2FA, and access role-based/protected routes with rate-limited sign-in.

Quick Start

Tell the agent to generate the Better Auth server setup for your TypeScript backend, including required environment variables, an auth.ts configuration, and the CLI commands to generate and run migrations.
