    Overview

    NextAuth.js is a complete open source authentication solution for Next.js applications.

    It is designed from the ground up to support Next.js and Serverless.

    Getting Started

    npm install --save next-auth
    

    The easiest way to continue getting started, is to follow the getting started section in our docs.

    We also have a section of tutorials for those looking for more specific examples.

    See next-auth.js.org for more information and documentation.

    Features

    Flexible and easy to use

    • Designed to work with any OAuth service, it supports OAuth 1.0, 1.0A and 2.0
    • Built-in support for many popular sign-in services
    • Supports email / passwordless authentication
    • Supports stateless authentication with any backend (Active Directory, LDAP, etc)
    • Supports both JSON Web Tokens and database sessions
    • Designed for Serverless but runs anywhere (AWS Lambda, Docker, Heroku, etc…)

    Own your own data

    NextAuth.js can be used with or without a database.

    • An open source solution that allows you to keep control of your data
    • Supports Bring Your Own Database (BYOD) and can be used with any database
    • Built-in support for MySQL, MariaDB, Postgres, Microsoft SQL Server, MongoDB and SQLite
    • Works great with databases from popular hosting providers
    • Can also be used without a database (e.g. OAuth + JWT)

    Secure by default

    • Promotes the use of passwordless sign in mechanisms
    • Designed to be secure by default and encourage best practice for safeguarding user data
    • Uses Cross Site Request Forgery Tokens on POST routes (sign in, sign out)
    • Default cookie policy aims for the most restrictive policy appropriate for each cookie
    • When JSON Web Tokens are enabled, they are signed by default (JWS) with HS512
    • Use JWT encryption (JWE) by setting the option encryption: true (defaults to A256GCM)
    • Auto-generates symmetric signing and encryption keys for developer convenience
    • Features tab/window syncing and keepalive messages to support short lived sessions
    • Attempts to implement the latest guidance published by Open Web Application Security Project

    Advanced options allow you to define your own routines to handle controlling what accounts are allowed to sign in, for encoding and decoding JSON Web Tokens and to set custom cookie security policies and session properties, so you can control who is able to sign in and how often sessions have to be re-validated.

    TypeScript

    NextAuth.js comes with built-in types. For more information and usage, check out the TypeScript section in the documentation.

    The package at @types/next-auth is now deprecated.

    Example

    Add API Route

    import NextAuth from "next-auth"
    import Providers from "next-auth/providers"
    
    export default NextAuth({
      providers: [
        // OAuth authentication providers
        Providers.Apple({
          clientId: process.env.APPLE_ID,
          clientSecret: process.env.APPLE_SECRET,
        }),
        Providers.Google({
          clientId: process.env.GOOGLE_ID,
          clientSecret: process.env.GOOGLE_SECRET,
        }),
        // Sign in with passwordless email link
        Providers.Email({
          server: process.env.MAIL_SERVER,
          from: "<no-reply@example.com>",
        }),
      ],
      // SQL or MongoDB database (or leave empty)
      database: process.env.DATABASE_URL,
    })

    Add React Component

    import { useSession, signIn, signOut } from "next-auth/client"
    
    export default function Component() {
      const [session, loading] = useSession()
      if (session) {
        return (
          <>
            Signed in as {session.user.email} <br />
            <button onClick={() => signOut()}>Sign out</button>
          </>
        )
      }
      return (
        <>
          Not signed in <br />
          <button onClick={() => signIn()}>Sign in</button>
        </>
      )
    }
