In this article, you will learn how to develop a functional website to authenticate your users and protect their identity and access to the site using Twilio Verify. The tutorial requires Python 3.6 or newer, Flask framework, python-twilio package, and environment variables. To start, create a project directory, set up the environment, create a database file of eligible users, plan the logic of the project, and design the user login page. The flow of logic for the project includes sending a one-time passcode to the user's phone number after the user enters their email on the website homepage. The user is then prompted to enter the verification code they received from their phone to verify their identity. If the verification code is correct, the user is redirected to another route where they can view their account information.
