Auth0 Makes it Easy

Product attributes that simplify identity for developers, created by experts in security.


No more closed, checkbox-based configuration tools. Auth0 allows you to fully customize any stage of the authentication and authorization pipeline to adapt to new policies, new applications, and new platforms.

Simple APIs

Connecting to a robust, simple and secure HTTPS API is key to allowing seamless integration with other tools and experiences. Auth0 allows you to authenticate and authorize apps and APIs with any identity provider running on any stack on any device or cloud.


It's critical to support multiple identity providers. Auth0 makes it easy for you to give  your users the ability to authenticate with the credentials they are most familiar with. Enterprise, social, or app-specific. Auth0’s widget gives you a fully customizable, enterprise-ready login/registration box with just a few lines of JavaScript.

Standard Protocols

Auth0 supports industry standards such as SAML, OpenID Connect, JSON Web Token, OAuth 2.0, OAuth 1.0a, WS­-Federation and OpenID.


Applications are now built on a broad spectrum of technology stacks. Auth0 provides SDKs for all popular web, mobile and native platforms, allowing for deep integration with the language and stack of your preference.
