Auth0
Auth0 is a cloud-based identity platform that handles authentication and authorisation for applications. It provides login, registration, social sign-in, multi-factor authentication, and single sign-on capabilities as a service. Rather than building and maintaining identity infrastructure, developers integrate Auth0 and configure it through a dashboard. For non-technical readers, Auth0 is the service that handles "who are you?" and "what are you allowed to do?" for applications. When you log in with Google, use fingerprint authentication, or access multiple applications with one account, Auth0 (or similar services) often powers these features behind the scenes. It removes the burden of building and securing login systems. Auth0 was founded in 2013 and acquired by Okta in 2021, making it part of a larger identity platform. It supports standards like OAuth 2.0, OpenID Connect, and SAML, ensuring compatibility with enterprise systems and third-party services.
Official WebsiteWhen to use Auth0
Use Auth0 when you need robust authentication without building it yourself. It's appropriate for web applications, mobile apps, single-page applications, and APIs that need user login, social sign-in, or integration with enterprise identity providers.
Auth0 is particularly valuable when security and compliance matter: the platform handles best practices for password storage, implements multi-factor authentication, and maintains compliance certifications. It's also useful when you need to support multiple identity providers or single sign-on across applications.
Why choose Auth0?
Teams choose Auth0 to avoid the complexity and risk of building identity systems. Authentication seems simple but involves subtle security concerns: password hashing, token management, brute force protection, and compliance with regulations. Auth0 handles these with a team dedicated to identity security. The platform's flexibility supports simple use cases and complex enterprise requirements alike.
