Overview

Auth0 is an enterprise identity platform that provides authentication, authorization, and user management as a service. It supports a wide range of identity protocols including OAuth 2.0, OpenID Connect, SAML, and WS-Federation, making it suitable for both consumer and enterprise applications.

The platform offers Universal Login, a hosted and customizable login page that handles all authentication flows securely. Auth0 supports social login with 30+ providers, enterprise connections like Active Directory and LDAP, and database connections with custom password policies. Advanced features include anomaly detection, breached password detection, and adaptive MFA.

For developers, Auth0 provides SDKs for every major platform and framework. The Next.js SDK offers server-side session management, API route protection, and token handling. Auth0 Actions allow you to customize authentication flows with serverless functions triggered at specific points in the login pipeline.
