SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

ASP.NET Core apps often struggle to implement secure, maintainable authentication and authorization. This guide covers JWT bearer tokens, OpenID Connect, ASP.NET Identity, policy-based authorization, and safe practices for protecting APIs and web UI.

Core Features & Use Cases

  • JWT Bearer authentication for APIs and web apps.
  • OpenID Connect integration for external identity providers.
  • Policy-based authorization for fine-grained access control.
  • Identity-driven user management with secure password handling and MFA guidance.
  • Endpoint protection patterns for common app architectures (API, Blazor, MVC).

Quick Start

Configure authentication and authorization in your ASP.NET Core project by following this guidance to implement JWT-based API security and policy-based access control.

FAQPage Schema
How do I implement JWT bearer authentication in an ASP.NET Core API?

Policy-based authorization in ASP.NET Core enables fine-grained access control by defining policies that evaluate user claims to protect specific endpoints. This approach satisfies requirements for claims-based authorization and secure endpoint protection across MVC and API architectures.

Can I integrate external OpenID Connect identity providers with ASP.NET Core?

OpenID Connect integration with ASP.NET Core supports connecting to external identity providers for secure user authentication. This covers configuring OIDC middleware to handle identity management and token validation within your web application.

What is the best way to apply claims-based authorization in ASP.NET Core web apps?

Claims-based authorization in ASP.NET Core is best applied through policy-based authorization, allowing fine-grained access control by evaluating user claims. This approach secures web UI and API endpoints by defining specific policy requirements.

Does this ASP.NET Core authentication guidance cover MFA and secure password handling?

ASP.NET Core authentication guidance includes identity-driven user management with secure password handling and MFA guidance. It integrates ASP.NET Identity to enforce safe practices for protecting APIs and web UI interfaces.

Why use policy-based authorization over basic role checks in ASP.NET Core APIs?

Policy-based authorization in ASP.NET Core provides fine-grained access control beyond basic role checks by evaluating complex claims-based logic. This approach ensures robust authorization and secure endpoint protection for APIs and Blazor applications.
