🔐 Authentication in Python APIs – Part 3: Full Client + Server with Basic Auth
Welcome to Part 3 of our Python API Authentication series!
In this video, we build a fully functional Basic Authentication system using FastAPI for the server and requests for the client — a complete REST API workflow with authentication.
💡 What You'll Learn:
Set up Basic Auth in FastAPI (server.py)
Build a Python client to access both public & private endpoints
Use HTTPBasicAuth from the requests library
Securely validate user credentials
Understand headers, status codes, and security principles
🧪 Bonus: We also test the flow with curl and discuss how to extend it with OAuth2 or JWT!

⚠️ Disclaimer
This video is for educational purposes only. Always use proper authentication methods (such as OAuth2 or JWT) in production environments. Basic Authentication is only suitable for specific, low-risk use cases or internal APIs.
The concepts, code, and demonstrations are provided to help you understand API Key–based authentication using FastAPI in a development setting.
When implementing authentication in real-world or production environments, always:
• Follow industry-standard security guidelines
• Conduct application-specific security reviews
• Refer to official documentation and ensure compliance with data protection regulations
