This blog post discusses the drawbacks of password-based authentication and introduces passwordless authentication, which allows user verification without using passwords.
The post focuses on how to implement passwordless authentication using Amazon Cognito, a fully managed service that provides user sign-up, sign-in, and access control. The blog post goes through the steps of setting up a Cognito User Pool, configuring the user pool client for the frontend, implementing custom authentication flows using Lambda hooks, and handling the authentication flow state machine.
The post includes code snippets and an explanation of how each part of the authentication flow works.
