Master the OpenID Authorization API 1.0. This guide shows you how to build a decoupled authorization system using Python and FastAPI.

Auth0's platform is a  identity management solution, offering insights into authentication, authorization, and user management for web and mobile applications. Through articles, tutorials, and documentation, Auth0 offers insights into securing applications with modern identity protocols like OAuth and OpenID Connect. Developers can learn about implementing single sign-on (SSO), multi-factor authentication (MFA), and user authorization policies to enhance application security and user experience.

The OpenID AuthZEN Authorization API 1.0 provides a standardized way to decouple authorization logic from applications. It defines how Policy Enforcement Points (PEPs) communicate with Policy Decision Points (PDPs) through two main APIs: Access Evaluation for permit/deny decisions and Search for listing authorized entities. The guide demonstrates building a document management system in Python with FastAPI, implementing both a PDP that evaluates policies based on document classification and user roles, and a PEP that queries the PDP for authorization decisions. This architecture enables interoperability and allows switching authorization engines without changing application code.
