To build a website that allows users to upload files and provide their own input while protecting user identity, this tutorial uses Flask and Twilio Verify. A free or paid Twilio account is required for sending verification tokens via SMS to users' phones after they enter their email on the website homepage. The user must then enter the verification code received from their phone to access the site's upload feature. The project incorporates security measures such as two-factor authentication, password handling, and file type validation to prevent malicious activity. Once authenticated, users can submit an image file in .jpg or .png format, which is stored in the project directory's "UPLOADS" folder. The tutorial covers setting up a development server, creating a database of eligible users, planning the logic of the project, building the user login page, generating verification codes with Twilio Verify, verifying user input, and displaying a success message.
