Passwordless – Enable User Sign-Up with SMS via AWS Lambda

In plain words

Passwordless is an AWS Lambda function that enables user sign-up and authentication through SMS instead of traditional passwords. It streamlines the registration process by sending verification codes via text message, eliminating the need for users to create and remember passwords. Designed for developers building applications on AWS, it simplifies identity management while reducing friction in the sign-up experience. The solution is available as open-source code on GitHub.
