.NET 10 🔥🚀 : Secure a .NET 10 Web API with JWT - Issuer/Audience/Key Validation

In this video, we’ll build JWT authentication end-to-end in a .NET 10 Web API (Controllers). You’ll learn how to: Install the JWT / JwtBearer packages Create a token issuing endpoint (/auth/token) Configure AddAuthentication().AddJwtBearer() with issuer, audience, signing key, lifetime validation Add roles + claims and protect endpoints with [Authorize], roles, and policies Store secrets safely using user-secrets locally and environment variables in production Add Swagger Bearer authentication so you can test secured endpoints in Swagger UI Validate everything using curl, including common failure scenarios (401/403, expired/tampered token) If you’re building production-ready APIs, this is a must-have foundation before you add Identity, databases, or external providers. 📌 Source code structure included in the walkthrough (AuthController, SecureController, JWT options, Swagger setup). ✅ Don’t forget to like/subscribe — I post .NET + cloud + architecture content weekly.
