How to Verify an Email Address Using Python, Flask, and Twilio Verify

Twilio Verify is a service used for user verification through numeric codes sent via SMS, voice call, or email. The service is integrated with Flask and SendGrid to send emails to users. A dynamic template is created in SendGrid to hold the email content, and an API key is generated for authentication purposes. In Python, Twilio Verify is used to create a one-time passcode protected login system where users can verify their identity by entering a verification code sent via email. The system authenticates user credentials using Twilio Verify and redirects users to a success page upon successful verification.
