2FA Login with Laravel and Nexmo

This tutorial provides a step-by-step guide on integrating two-factor authentication with Nexmo Verify into a Laravel application. The process involves collecting the user's phone number at registration time, adding a field to the users table in the database, and modifying the login controller to send a verification request via Nexmo. After verifying the code provided by the user, the system logs them in automatically. The tutorial also touches on implementing additional security measures such as validating the incoming data, catching exceptions, and logging out the user after registration.
