Email Address Verification in FastAPI using Twilio Verify

Implementing email verification in a FastAPI application using Twilio Verify can help prevent fake accounts. The process involves configuring SendGrid and setting up an API key, dynamic template, and email integration with Twilio Verify. A virtual environment is created to install necessary packages, including FastAPI, python-dotenv, aiofiles, python-multipart, uvicorn, and the Twilio Python Helper library. An application settings file, config.py, is created to store configuration variables in a secure manner using environment variables from a .env file. The application includes endpoints for handling form submissions, sending verification codes via email, accepting code submissions, verifying codes, and displaying success pages. Once complete, the server can be run with uvicorn and tested by navigating to http://localhost:8000 and submitting an email address to receive a verification code.
