JWT Authentication in ASP.NET Core Web API – Part 3 | Auth Server, Resource Server & Refresh Tokens

This is Part 3 and the final video in the JWT Authentication series for ASP.NET Core Web API. In this session, we bring everything together and implement a complete, real-world JWT authentication system using an Authentication Server and multiple Resource Servers.

You will learn:
• How an Authentication Server (Token Issuer) works
• How Resource Servers validate JWT access tokens
• Why shared JWT validation logic is important
• How roles, claims, and policies are enforced
• How refresh tokens fit into secure authentication systems
• How JWT authentication is implemented in production-ready architectures

This video completes the JWT Authentication journey by demonstrating how modern ASP.NET Core Web APIs handle authentication and authorization in scalable, secure systems.

📌 Part 1 covered JWT fundamentals and token structure
📌 Part 2 explained the Auth Server vs Resource Server concepts
📌 Part 3 shows the complete real-time implementation

If you are building secure APIs, microservices, or enterprise applications, this series will give you a clear and practical understanding of JWT authentication.
