Authentication Layer

Introduction

Secure your API with modern authentication flows. We’ll implement robust login, token, and access control mechanisms used in production.

Included in this lesson

• Setting up JWT-based authentication

• Protecting private routes with middleware

• Implementing refresh tokens and session expiration

• Adding role-based access control (RBAC)

Why it matters

Auth is hard to get right — we make it clear, practical, and secure with a proven, modular approach that works at scale.
