What does Auth0 do?
Auth0 is an identity and access management platform that handles authentication and authorization for applications. It lets developers add secure login systems to their apps without building them from scratch. This includes features like social logins (Google, Facebook), multi-factor authentication, single sign-on (SSO), and passwordless options. It manages the entire user identity lifecycle, from sign-up to profile management, while keeping security as the top priority.
The platform stands out with its extensive developer toolkit, offering over 30 SDKs and quickstart guides for popular frameworks like React, Angular, Node.js, and iOS. It provides a centralized token vault to manage API access for AI agents and tools, and includes fine-grained authorization controls for restricting data access in AI systems. Auth0 handles massive scale, processing over 10 billion authentications monthly while blocking billions of attack attempts.
Auth0 benefits development teams building web applications, mobile apps, and AI-powered services who need reliable user authentication. It's particularly valuable for B2B SaaS companies requiring enterprise features like SCIM and SSO, consumer apps needing frictionless signup flows, and teams implementing AI agents that require secure API access. Companies like Mazda, Pfizer, and Mercado Libre use it to secure their applications.
