🔥 In Part 4 of our Google Cloud Functions Training series, we dive into securing your cloud functions using JWT (JSON Web Tokens). Learn how to protect your serverless endpoints and ensure only authorized users can access your backend logic.

✅ What you’ll learn in this video:
✔️ What JWTs are and how they work
✔️ Generating and decoding JWTs securely
✔️ Setting up middleware-style validation in Google Cloud Functions
✔️ Using libraries like jsonwebtoken (Node.js)
✔️ Validating token signatures and payload claims
✔️ Securing routes and handling authentication errors
✔️ Best practices for token expiration and refresh
✔️ Integrating JWT checks with Firebase Auth or custom auth systems

💡 Why JWT Validations Matter:
🔹 Critical for protecting sensitive endpoints in your app
🔹 Ensures only authenticated users can trigger backend logic
🔹 Works seamlessly with serverless architecture
🔹 Foundation for building scalable, secure full-stack apps
