You will deploy a Vonage Verify 2FA client as a microservice to AWS Lambda using Python and Flask, leveraging Serverless technology, with the goal of implementing multi-factor authentication for web services, providing an extra layer of security against unauthorized access. To complete this tutorial, you need a Vonage API account, clone the provided GitHub repository, set up environment variables, install dependencies, run the application locally, deploy it to AWS Lambda, and secure the app before accessing its URL. The client offers four URL endpoints: one for testing, one for requesting a 2FA code, one for checking a code, and one for cancelling a request, with each endpoint providing a specific functionality in the authentication process.
