## Description

Auth0 provides an identity platform for securing applications, APIs, and digital services, with Fine-Grained Authorization (FGA) designed to help developers manage complex permissions at scale. Built on OpenFGA, an open-source project in the Cloud Native Computing Foundation, Auth0 FGA uses relationship-based access control to separate authorization logic from application code. It supports access decisions across users, AI agents, and resources, including the needs of multi-tenant B2B applications, collaborative features, and retrieval-augmented generation systems.

Developers can use FGA to define fine-grained policies for sharing, roles, delegation, time limits, and other access conditions. The service offers APIs, SDKs, a CLI, IDE integrations, and management interfaces, alongside centralized permission checks and audit trails. Auth0 positions FGA to help enforce least-privilege access, protect APIs exposed to AI agents, and support compliance efforts such as GDPR and HIPAA. The company also offers documentation, a playground, technical resources, and options to get started or contact its team. Auth0 FGA is presented as an enterprise-scale service with low-latency checks and a 99.99% availability SLA.
