Serverless Phone Verification with Twilio Verify and Twilio Functions

Twilio Verify and Twilio Functions can be used to securely verify users' phone numbers from a web application, reducing fraud and increasing reliability of notifications. To do this, developers need a Twilio account, the Twilio CLI, and a Verify Service created in the Twilio console. The serverless toolkit is used to deploy the project, which includes two functions: one to send a one-time password (OTP) to the user's phone or email, and another to verify that the OTP is correct. The application can be deployed with just two API calls and one web page, allowing developers to easily integrate phone verification into their existing applications.
