Overview

This skill describes Better Auth, a framework-agnostic authentication and authorization framework for TypeScript. It shows how to add email/password, social OAuth, 2FA, passkeys, magic links, and multi-tenant features with built-in session and plugin support. The guide focuses on practical installation, configuration, and common integration patterns across frameworks.

How this skill works

Better Auth exposes a server instance that handles auth logic, database operations, API routes, and a client instance with hooks and methods for sign-in, session handling, and plugin features. It integrates with direct database drivers or ORM adapters (Drizzle, Prisma, Kysely, MongoDB) and uses a plugin system to add advanced features like 2FA, passkeys, username auth, magic links, and organization/multi-tenancy. Routes are mounted per-framework with small adapter helpers for Next.js, SvelteKit, Nuxt, Hono, Express, and others.

When to use it

Adding authentication to TypeScript/JavaScript apps regardless of framework
Implementing email/password, social OAuth, magic links, passkeys, or 2FA
Building multi-tenant or organization-backed auth flows
Needing type-safe session management and user APIs
Replacing or standardizing auth across frontend and backend stacks

Best practices

Store secrets in environment variables and use HTTPS in production
Use secure cookies and tune session expiration for your app
Run migrations after adding plugins or changing schema
Enable rate limiting and email verification in production
Leverage TypeScript types and ORM adapters for predictable data models

Example use cases

Set up email/password sign-up and auto sign-in with post-signup redirect
Add GitHub and Google OAuth for social sign-on and handle new-user flows
Enable two-factor authentication with TOTP and trusted devices via plugin
Implement passkey (WebAuthn) registration and sign-in for passwordless auth
Create organization CRUD and invitation flows for multi-tenant apps

FAQ

Better Auth supports direct drivers (SQLite, Postgres, MySQL, MongoDB) and adapters for Drizzle, Prisma, Kysely, and MongoDB clients.

How do I mount auth routes in my framework?

Use provided handlers or adapters (toNextJsHandler, svelteKitHandler, toNodeHandler, Hono integration) to map /api/auth/* to the Better Auth server instance.
