Authentication for Next.js
Open Source. Full Stack. Own Your Data.
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.
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.
- 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…)
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)
- 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.
You can install the appropriate types via the following command:
npm install --save-dev @types/next-auth
If you encounter any problems with the types package, please create an issue and add the typescript label to it.
Alternatively, you can open a pull request directly with your fixes on the DefinitelyTyped repository, where you'll find a next-auth subfolder.
