Duo two-factor authentication for ASP.NET web applications

branch: master


duo_dotnet - Duo two-factor authentication for .NET web applications

Duo provides simple two-factor authentication as a service via:

  1. Phone callback
  2. SMS-delivered one-time passcodes
  3. Duo mobile app to generate one-time passcodes
  4. Duo mobile app for smartphone push authentication
  5. Duo hardware token to generate one-time passcodes

This package allows a web developer to quickly add Duo's interactive, self-service, two-factor authentication to any web login form - without setting up secondary user accounts, directory synchronization, servers, or hardware.

What's here:

  • js - Duo Javascript library, to be hosted by your webserver.
  • DuoWeb - Duo .NET SDK to be integrated with your web application
  • DuoTest - Unit tests for the SDK
