ck:better-auth

Better Auth is a comprehensive, framework-agnostic authentication and authorization library designed specifically for modern TypeScript applications. It provides a modular and secure foundation for managing user lifecycles, enabling developers to quickly integrate robust security features into projects built with Next.js, Nuxt, SvelteKit, Remix, Astro, Hono, or Express. The skill simplifies the complexity of identity management, allowing teams to focus on core product functionality while offloading credential handling, session persistence, and security compliance.

• Full support for traditional email/password authentication with built-in verification and password reset flows.

• Extensive social provider integration including GitHub, Google, and other OAuth 2.0 services.

• Advanced security features including Two-Factor Authentication (2FA/TOTP), WebAuthn passkeys, and magic link authentication.

• Built-in session management with persistent tracking and automatic token handling.

• Multi-tenant organization support, making it ideal for SaaS platforms requiring team-based access control.

• Role-Based Access Control (RBAC) and configurable rate limiting to protect API endpoints against brute force and abuse.

• Extensible plugin architecture allowing for custom business logic to be injected into the auth lifecycle.

• Prerequisites: A TypeScript environment with an accessible database (e.g., PostgreSQL, MySQL, SQLite, or Turso) and basic knowledge of the chosen framework's API routing.

• Implementation: Requires configuring environment variables, mounting the API handler within the framework's route structure, and generating database schemas via the Better Auth CLI.

• Inputs/Outputs: Processes user credentials and OAuth tokens, producing secure session cookies or JWTs. The client library provides reactive hooks for frontend state management.

• Operational Constraints: Ensure the BETTER_AUTH_SECRET is securely stored in environment variables; always enable rate limiting and migrate database schemas before production deployment to maintain consistency.
