Production-Ready User Auth with Airtable & JWT

This n8n workflow delivers a complete, production-ready user authentication system powered by Airtable as the database. It features dedicated flows for user sign-up—validating unique emails, SHA256 hashing passwords (Base64 encoded), and storing user data—and login, which verifies credentials and issues JWT tokens containing user ID and email. Additional protected flows handle CRUD operations like retrieving and updating user details via JWT-authenticated requests.

Key benefits include enhanced security through hashed passwords and JWT for stateless auth, eliminating the need for a custom backend database. It's highly scalable, easy to deploy via n8n webhooks, and saves weeks of development time for auth features. The workflow includes error handling for common cases like duplicate emails or invalid passwords, ensuring reliable API responses.

Use cases span web apps, SaaS platforms, internal tools, and even healthcare systems for secure lab results access. Adapt it for patient portals by linking user auth to Airtable records of lab data, enabling role-based access. Includes a YouTube demo for quick setup: https://www.youtube.com/watch?v=gKcGfyq3dPM.
