Auth.js

Auth.js (formerly NextAuth.js) is a complete open-source authentication solution for Next.js applications. It provides a flexible, secure, and easy-to-use authentication system that supports various providers (OAuth, email, credentials) and adapters (databases).

Building authentication from scratch is complex and error-prone. Auth.js handles the intricate details of session management, token handling, CSRF protection, and provider integrations, allowing developers to focus on building features rather than reinventing authentication.
