# danilop/LambdAuth

A sample authentication service implemented with a server-less architecture, using AWS Lambda to host and execute the code and Amazon DynamoDB as persistent storage. This provides a cost-efficient solution that is scalable and highly available and can be used with Amazon Cognito for Developer Authenticated Identities.

## What it is
LambdAuth is a sample serverless authentication service built on AWS Lambda with Amazon DynamoDB for user storage. It handles user signup with email validation, login, password change and reset, and integrates with Amazon Cognito Developer Authenticated Identities.

## Use cases
- implement serverless user authentication on AWS
- sign up users with email verification using Lambda
- issue auth tokens for Cognito developer authenticated identities
- add password reset emails to a serverless app
- store salted password credentials in DynamoDB

## When to choose
- you want a learning sample of serverless auth on AWS Lambda
- you need a minimal, cost-efficient auth backend integrated with Cognito
- you are following the AWS Lambda in Action book examples

## When to avoid
- you need a production-ready auth solution (use Amazon Cognito User Pools instead)
- you want an actively maintained project
- you are not on AWS or need non-JavaScript tooling

## Facets
- artifact type: application
