Struggling with expired JWTs, token leaks, or broken auth flows? In this video I show a practical, secure implementation of refresh tokens and how to properly build a ClaimsPrincipal in ASP.NET Core — step-by-step, production-minded, and easy to follow.
What you’ll learn:
Why refresh tokens are essential (vs. long-lived access tokens)
How to design a secure refresh flow and prevent replay attacks
How to reconstruct ClaimsPrincipal after token refresh (so roles/claims persist)
