What is Auth.js?

Auth.js is a runtime agnostic library based on standard Web APIs that deeply integrates with modern JavaScript frameworks via additional libraries that wrap the core functionality and tailor it to the framework’s best practices. This documentation covers [email protected] and later and all other frameworks under the @auth/* namespace. Documentation for [email protected] can still be found at next-auth.js.org.
