SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Authentication and authorization prevent unauthorized access by verifying identities and enforcing permission rules on protected endpoints.

Core Features & Use Cases

JWT Bearer Authentication for APIs: Validate issuer, audience, lifetime, and signing keys for stateless access control.
Policy-based Authorization: Replace brittle role strings with composable policies using claims and custom requirements.
OpenID Connect + External Identity: Delegate sign-in to an external provider using standards-based authentication flows.
API Key Authentication & Claims Access: Support simpler authentication patterns and access the current user’s claims in handlers.

Quick Start

Implement JWT bearer authentication and an authorization policy in your ASP.NET Core project so protected endpoints are accessible only to authenticated users meeting your rule set.

FAQPage Schema

How do I implement JWT bearer authentication for an ASP.NET Core minimal API?▼

JWT bearer authentication validates issuer, audience, lifetime, and signing keys for stateless API access control in ASP.NET Core. You configure strict token validation parameters and apply authorization policies to protect minimal API endpoints from unauthorized requests.

What is policy-based authorization in ASP.NET Core and when should I use it?▼

Policy-based authorization in ASP.NET Core replaces brittle role strings with composable policies using claims and custom requirements. Use it to enforce granular permission rules on protected endpoints based on user claims rather than simple role checks.

How do I integrate OpenID Connect external providers into ASP.NET Identity?▼

Integrating OpenID Connect delegates sign-in to external identity providers using standards-based authentication flows. You configure authentication handlers in ASP.NET Core to manage external login alongside ASP.NET Identity for local user management.

Does ASP.NET Core support API key authentication and accessing current user claims?▼

ASP.NET Core supports API key authentication patterns alongside JWT bearer tokens. You can access the current user's claims directly within authentication handlers to enforce permission rules and verify identity on protected API endpoints.

Do I need ASP.NET Identity to use JWT bearer authentication and authorization policies?▼

ASP.NET Identity is required for user management when implementing JWT bearer authentication and policy-based authorization. You handle secret management via configuration or secret stores to securely manage token signing keys and protect API endpoints.
