In today’s rapidly evolving digital landscape, security is paramount, especially when handling user data and controlling access to various resources. Role-based authentication is a robust method for ensuring that users only have access to the parts of an application that are relevant to their roles.

In this article, we’ll delve into the implementation of role-based authentication using FastAPI, a modern, fast (hence the name), web framework for building APIs with Python.

Why we need Need for Role-Based Authentication

Imagine a bustling startup environment, where multiple users with varying responsibilities interact with an application. Without proper authentication mechanisms, sensitive data could be compromised, leading to severe consequences. Role-based authentication addresses this challenge by assigning specific roles to users, dictating their access levels within the system.
