Google Apps Script Login System with Dynamic Multiple Pages

🚀 In this video, I’ll show you how to create a secure login system with Google Apps Script (GAS). We’ll build a complete web app that includes: 🔑 Login & Logout with Google Sheets authentication ⏳ Token-based session management (3-hour expiry) 📑 Dynamic sidebar menu based on user access 📊 Switching between Dashboard, Reports, and Settings without redirects 👉 One of the biggest challenges in Google Apps Script is that it doesn’t support direct redirects like PHP or Node.js. In this tutorial, I’ll show you how we solve that problem using localStorage and dynamic HTML loading. 💡 This project is perfect if you want to build your own inventory system, invoice tracker, or admin dashboard using just Google Apps Script + Google Sheets. 🔗 Project Sheet Template: 👉 https://docs.google.com/spreadsheets/... 💰 Support My Work (PayPal): 👉 https://paypal.me/ronyrahaman2000 ✅ Don’t forget to Like, Share & Subscribe for more Google Apps Script tutorials!
