Learn how to secure your Ruby on Rails RAG application using Auth0 FGA to prevent data leakage and implement fine-grained, identity-aware document retrieval.

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.

A step-by-step guide to securing a Ruby on Rails RAG (Retrieval-Augmented Generation) application using Auth0 for authentication and Auth0 FGA (Fine-Grained Authorization) for document-level access control. The tutorial covers setting up OmniAuth-based login, defining a ReBAC authorization model in Auth0 FGA, creating relationship tuples between users and documents, and filtering vector search results to only include documents the authenticated user is permitted to access — preventing sensitive data from leaking into LLM context.
