Passwordless Authentication With PHP Using Twilio Verify

This article explains how passwordless authentication works and demonstrates its implementation using PHP and Twilio Verify API. Passwordless authentication is a method that does not require a password or any other knowledge-based secret to log a user into a system, instead relying on unique one-time codes (OTP) or magic links sent via email, push notification, or text message. The tutorial covers the benefits and drawbacks of this approach, as well as how to create an application that uses passwordless authentication.
