CodePen Training – Mastering CodePen: Firebase Config & Authentication Setup

Welcome to Part 6 of the Mastering CodePen series! In this session, we’ll integrate Firebase Authentication with your CodePen project—adding real login/signup functionality using Google Firebase, right from your browser environment.

✅ What you’ll learn in this video:
✔️ Setting up a Firebase project from the Firebase Console
✔️ Adding Firebase SDK scripts to CodePen via CDN
✔️ Initializing Firebase in your JavaScript panel (firebaseConfig setup)
✔️ Implementing email/password signup and login
✔️ Using Google Sign-In as a provider
✔️ Displaying authenticated user data (name, email, UID)
✔️ Handling login states: show/hide content conditionally
✔️ Writing clean authentication logic in a CodePen environment

💡 Why Firebase Auth in CodePen is Awesome:
🔹 Zero backend needed—Firebase handles auth and identity
🔹 Great for prototyping real login flows quickly
🔹 Helps you understand how authentication connects with front-end apps
🔹 Prepares you for larger apps with auth flows (React, Vue, etc.)
