How to send an SMS magic link for one-click phone verification

Sending an SMS magic link for one-click phone verification is a widely popular method that improves the user experience by creating a one-click verification process. This tutorial explains how to implement SMS magic links using Twilio Verify API, which abstracts the more annoying parts of sending an SMS and focuses on business logic. The process involves inputting a phone number or logging in with an existing phone number associated account, sending an SMS with a verification link, clicking the link, validating the provided OTP, and setting a session or sending a callback to indicate verification success. To send magic links, developers need to create a Twilio Verify Service, deploy a custom template for testing and production, add environment variables, and implement verification logic using Twilio's stateless verification tracking features. The process provides a user-friendly way to validate phone numbers for authentication or authorization while offering strong security and fraud prevention measures.
