Auth0 is an identity and access management platform that handles user authentication, authorization, and single sign-on across web, mobile, and machine-to-machine applications.
Auth0 is an identity and access management platform designed to handle authentication and authorization for web, mobile, API, and machine-to-machine applications. It provides a centralized, standards-based way to secure human users, AI agents, and services, reducing the complexity of building and maintaining custom auth systems. Auth0’s primary purpose is to help organizations implement secure login, access control, and identity workflows that scale with their applications and user base.
Key features include support for multiple authentication methods such as username/password, passwordless, social logins, enterprise identity providers (e.g., SAML, OIDC, LDAP, Azure AD), and multi-factor authentication. Auth0 offers fine-grained authorization through role-based access control (RBAC), permissions, and rules or actions that allow custom logic at various points in the authentication pipeline. It also provides secure token issuance using OAuth 2.0 and OpenID Connect, user management with profiles and metadata, and built-in anomaly detection to mitigate suspicious login activity. Developers can integrate Auth0 via SDKs, hosted login pages, or APIs, and manage configurations through a dashboard or infrastructure-as-code.
