Welcome, seeker of code wisdom! In today's lesson, we will unveil the secrets of authentication and authorization. We will elucidate these security protocols, construct a basic authentication system with Node, and guide you in creating an engaging login page using React.

Join us as we unravel the intricacies of authentication and authorization. Consider them as sentinels of a fortress—authentication verifies the user's identity, it's akin to a sentry poised with the question: "Who goes there?" Conversely, authorization, acting much like a gatekeeper, determines: "What can you do here?" These security precautions cast their protective aura over every virtual transaction, ranging from accessing a library to operating a banking application.

To ensure the safety of the data realm, authentication and authorization combine their strengths to form an impregnable fortress. Imagine a banking system where anyone could waltz right in and claim they are the king! It's these qualitative security layers that prevent such chaos. The system, acting much like a bank sentry, authenticates users by verifying their identity, then authorizes services according to the user's account type, ensuring only rightful access to resources.

The magic of Node.js, a humble server-side scripting JavaScript runtime, awaits us! By harnessing the power of JavaScript, we will conjure up a basic authentication system. Our hard-coded user data will manifest, similar to a parchment holding a simple spell!
