In the ever-evolving landscape of web applications, security is non-negotiable. Python, a language celebrated for its simplicity, versatility, and extensive library support, is a popular choice for developers building applications.

However, no matter how robust your Python app may be, it’s crucial to implement strong security measures, especially when it comes to user authentication. One powerful solution that stands out is OAuth.

Understanding OAuth Basics

OAuth, short for Open Authorization, is a widely adopted framework that provides secure authorization over the internet. Its primary use case involves allowing third-party applications to access resources on a user’s behalf without exposing their credentials.

Consider this scenario: You’re building a Python application that needs to fetch data from a user’s Google Drive. Instead of asking the user to share their Google credentials, which would be a security nightmare, OAuth enables a secure, token-based authentication process.

Here’s a simplified breakdown of the OAuth flow:

1. User Requests Access: The user initiates the process…
