NextAuth.js

Authentication for Next.js

Open Source. Full Stack. Own Your Data.

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.

This is a monorepo containing the following packages / projects:

1. The primary next-auth package
2. A development test application
3. All @next-auth/*-adapter packages
4. The documentation site

Getting Started

``
npm install 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

$3

- 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…)

$3

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)

$3

- Promotes the use of passwordless sign-in mechanisms
- Designed to be secure by default and encourage best practices for safeguarding user data
- Uses Cross-Site Request Forgery (CSRF) 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 encrypted by default (JWE) with A256GCM
- Auto-generates symmetric signing and encryption keys for developer convenience
- Features tab/window syncing and session polling 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.

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

Example

$3

`javascript
// pages/api/auth/[...nextauth].js
import NextAuth from "next-auth"
import AppleProvider from "next-auth/providers/apple"
import GoogleProvider from "next-auth/providers/google"
import EmailProvider from "next-auth/providers/email"

export default NextAuth({
secret: process.env.SECRET,
providers: [
// OAuth authentication providers
AppleProvider({
clientId: process.env.APPLE_ID,
clientSecret: process.env.APPLE_SECRET,
}),
GoogleProvider({
clientId: process.env.GOOGLE_ID,
clientSecret: process.env.GOOGLE_SECRET,
}),
// Sign in with passwordless email link
EmailProvider({
server: process.env.MAIL_SERVER,
from: "",
}),
],
})
`

$3

The useSession() React Hook in the NextAuth.js client is the easiest way to check if someone is signed in.

`javascript
import { useSession, signIn, signOut } from "next-auth/react"

export default function Component() {
const { data: session } = useSession()
if (session) {
return (
<>
Signed in as {session.user.email}

signOut()}>Sign out

)
}
return (
<>
Not signed in

signIn()}>Sign in

)
}
`

$3

Use the to allow instances of useSession() to share the session object across components. It also takes care of keeping the session updated and synced between tabs/windows.

`jsx title="pages/_app.js"
import { SessionProvider } from "next-auth/react"

export default function App({
Component,
pageProps: { session, ...pageProps },
}) {
return (



)
}
``
