How to implement two-factor authentication in Asp. Net web forms

Question

Hi,

We have an old Asp.Net web forms application. Currently, it has a login page where the user will enter a username and password which will be verified against saved values in the SQL server database. Our management wants to implement a two-factor authentication on the website. I know how to use identity-based two-factor authentication in an asp.net core, however, I don't know how to implement the same on a web form. I searched Google and YouTube but couldn't find any useful links. I saw this on YouTube, but it describes mostly theory on the subject but no source code is provided: https://www.youtube.com/watch?v=2SIYclIN2jI&list=PLIoX3-mcY80gmA0hh9zrldIEwjOzCWqTY&index=1&ab_channel=RGEdu

Thanks

Hi @Sherpa,

Maybe you could try using ASP.NET Identity.

Microsoft official documentation provides relevant tutorials, I hope it will be helpful to you.
