Introducing AuthWarden: An Open-Source Authentication Library for FastAPI

#python #fastapi #backend #webdev

Authentication is one of those features that almost every backend application needs, yet implementing it properly can become surprisingly complex.

What starts as a basic login endpoint can quickly expand into JWT token management, refresh tokens, OAuth2, multi-factor authentication, role-based permissions, email verification, and password recovery.

As a backend developer, I wanted a more reusable approach.

So I started building AuthWarden.

What is AuthWarden?

AuthWarden is an open-source Python authentication library designed to simplify authentication and authorization workflows in FastAPI applications.

It provides modular building blocks that developers can integrate into their applications without having to repeatedly implement common authentication functionality.

Key Features

  • JWT Authentication: Access tokens, refresh tokens, and token revocation.
  • OAuth2: Integration options for external identity providers.
  • Multi-Factor Authentication: TOTP and backup-code support.
  • Authorization: Roles, permissions, and access scopes.
  • Account Management: Email verification and password recovery.
  • Database Integration: SQLAlchemy-backed storage and extensible interfaces.
  • Security: Login protection and configurable authentication behavior.

Getting Started

Install AuthWarden from PyPI:

pip install authwarden
Enter fullscreen mode Exit fullscreen mode

You can find integration instructions and examples in the official documentation.

Why Open Source?

I believe developer tooling becomes better through collaboration, feedback, and real-world usage.

That's why AuthWarden is released under the MIT license.

My goal is to continue improving its architecture, integrations, reliability, and developer experience.

Support AuthWarden ⭐

If you find AuthWarden useful or believe it could help other FastAPI developers, consider giving the project a star on GitHub.

Stars help increase the project's visibility and make it easier for developers to discover.

Contributions, issues, suggestions, and technical feedback are equally appreciated.

Let's Connect

I'd love to hear from developers who have implemented authentication systems in FastAPI.

What challenges have you faced, and what features would you expect from a reusable authentication library?

Thanks for reading, and happy coding!
