Overview

Auth.js is a set of open-source packages for implementing authentication across frameworks, platforms, and JavaScript runtimes. It supports OAuth 2.0 and OIDC providers, passwordless sign-in, Passkeys and WebAuthn, and database-backed or stateless sessions.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Choose providers, sessions, and databases around application requirements

Applications can combine many sign-in providers, email or passwordless flows, and Passkeys, with or without a database. Defaults include CSRF tokens on POST routes, restrictive cookie policies, and encryption when JSON Web Tokens are used.

For JavaScript applications choosing how authentication data and sessions work

It is a candidate for teams that want to reduce framework-specific authentication code while retaining control of data storage, providers, and session policies. Verify the relevant adapter and framework integration across sign-in, sign-out, session refresh, and account linking.

Review the Better Auth direction before choosing it for a new project

Auth.js is now part of Better Auth, and the README recommends Better Auth for new projects. A notable exception is a feature gap around stateless session management without a database. Because the Auth.js brand, next-auth repository and npm package, and older documentation names coexist, pin the intended integration and version. The license is ISC.
