Welcome to Part 17 of the Google Cloud Functions Training series! In this session, we’ll explore Authentication Methods for securing your Cloud Functions. Authentication ensures that only authorized users and services can access your APIs, protecting sensitive operations like database writes, file uploads, or admin actions.

✅ What You’ll Learn in This Video:
✔️ Overview of Firebase Authentication (email/password, OAuth providers, custom tokens)
✔️ Securing Cloud Functions with Firebase Auth tokens
✔️ Role-based access control (RBAC) using claims
✔️ Verifying ID tokens in Cloud Functions (server-side validation)
✔️ Using Google Identity Platform for advanced authentication flows

💡 Why This Step Matters:
🔹 Prevents unauthorized access to sensitive backend logic
🔹 Provides a scalable way to authenticate users across devices
🔹 Forms the backbone of secure client-server interactions
🔹 Prepares your app for enterprise-grade role and permission management
