# Authentication via API: sign-up, login, profile management with n8n and Airtable
This template implements a complete user management cycle — registration, login, and profile updates — using HTTP requests and Airtable as the data store. Ideal for teams needing a quick no-code authentication backend without building a custom database.
## Who it´s for
- Developers building MVPs without backend resources
- Startups using Airtable as a temporary database
- Product managers testing user registration flows
## What the automation does
- Handles HTTP POST requests for user sign-up, checking email uniqueness in Airtable
- Hashes passwords using cryptographic functions before storage
- Validates credentials on login by comparing password hashes
- Returns JSON responses indicating success or error status
- Retrieves and updates user profile data upon request
## What´s included
- Ready-to-use n8n workflow with Airtable backend authentication logic
- Trigger and handler logic based on Webhook
- Integrations with Airtable and HTTP API
- Basic written instructions for setup and adaptation
## Requirements for setup
- n8n account (self-hosted or cloud)
- Airtable account with a user table (email, password hash, profile fields)
- Webhook configuration access in n8n
- Basic understanding of REST APIs and JSON handling
## Benefits and outcomes
- Fast implementation of authentication without coding
- Time saved on backend development
- Use of Airtable as a lightweight NoSQL solution for MVPs
- Flexibility to adapt and scale during prototyping
- Ability to test user flows early in development
- Secure password storage via hashing
