Build Simple SMS Phone Verification with Twilio Verify and Python

`Building Simple SMS Phone Verification with Twilio Verify and Python involves creating a Flask application that collects user input, sends a verification request to Twilio's Verify API, and checks the token received by the user. The application uses Flask sessions to store the user's phone number and country code, allowing it to verify the token without asking for the phone number again. With just two API calls and two web pages, this process enables secure phone verification, reducing fraud and increasing reliability of notifications.
