This tutorial by Miguel Grinberg provides an easy-to-follow guide to implementing Two-Factor Authentication (2FA) using Twilio Verify, a service that enables businesses to validate users through various channels. The process involves four steps: creating a Twilio Verify service, configuring credentials, sending a verification code to the user's phone, and verifying the provided code. By following these steps, developers can add 2FA support to their applications without much hassle, protecting against fraud and unauthorized access.
