AppSheet Custom Login & Registration System (Step-by-Step)

In this video, we build a fully functional custom Login and Registration system in AppSheet — without using built-in security filters. You’ll learn how to: • Create Register and Login screens • Store logged-in users in a Logged In User table • Capture Device ID for multi-device sessions • Prevent duplicate sessions on the same device • Use grouped actions for login flow • Capture user roles dynamically • Control button visibility based on role Instead of relying on AppSheet’s default security filters, we build our own login logic using actions, slices, and expressions. This approach gives you: ✔ Full control over user sessions ✔ Multi-device support ✔ Role-based UI visibility ✔ Cleaner workflow customization In the next video, we’ll expand this into a complete role-based workflow system.
