Verifying Phone Number Ownership in ASP.NET Core Identity with Twilio Verify v2 and Razor Pages

In this post, the author demonstrates how to verify phone number ownership using Twilio Verify in an ASP.NET Core Identity application. The process involves sending a verification code to the user's phone number via SMS and checking if the provided code is correct. If the code is correct, the user's phone number is confirmed and stored in the database. The author uses version 2 of the Twilio Verify API, which allows for easier integration with ASP.NET Core Identity. The post provides a step-by-step guide on how to implement this functionality, including setting up the Twilio account, installing the necessary NuGet packages, and creating the required Razor Pages. The author also highlights some possible improvements that can be made to the implementation, such as adding a link to the verification page and displaying the verification status in the app.
