020 API Security Securing: Flask Basic Authentication Guide
🔐 *Flask Basic Authentication Guide*
Want to protect your Flask routes and secure your web API? This video walks you through implementing *Basic Authentication* in Flask — the simplest form of HTTP-based user validation.
---
✅ What You'll Learn:
What is Basic Authentication and when to use it
How to implement username & password protection in Flask
Creating protected routes and endpoints
Using `request.authorization` to access credentials
Returning proper status codes (401, 403, etc.)
Handling invalid or missing credentials
Real-world use cases and when to avoid basic auth
---
🔧 Tools & Libraries:
Flask (no external authentication packages needed)
Postman or curl for testing protected routes
Optional: Flask-HTTPAuth for easier scaling
---
⚠️ Security Note:
Basic Authentication *is not encrypted by default* — it's best used *only with HTTPS* or for internal tools. For production-grade systems, consider using *token-based authentication (JWT)* or **OAuth**.
