To implement 2-factor authentication (2FA) in your ASP.NET MVC C# application using SAML2 authentication with Azure AD, you'll need to make several configuration and code changes. Here's an overview of the steps involved: Set up your Azure AD application: Register your application in Azure AD and configure the necessary settings. Obtain the Entity ID and ACS URL for your application. Configure your application for SAML2 authentication: Install the appropriate NuGet packages for SAML2 authentication in your ASP.NET MVC application. For example, you can use the Kentor.AuthServices package. Update the web.config file with the SAML2 authentication settings, including the entity ID, ACS URL, and certificate information. Enable 2FA in Azure AD: Configure Azure AD to require 2FA for users. Assign the necessary users or groups to the Azure AD application. Update your authentication code: Implement the necessary code changes in your application to handle the SAML2 authentication response. Validate the SAML response and perform additional verification for the second factor of authentication. Here are some specific resources that provide detailed steps and examples for implementing SAML2 authentication with 2FA in an ASP.NET MVC application: Integrating SAML2-based Azure AD SSO with ASP.NET MVC using Kentor.AuthServices SAML2 Authentication with Kentor.AuthServices Please note that implementing 2FA involves complex configuration and code changes, and it's recommended to thoroughly test the implementation and follow best practices for security. It may also be helpful to consult with a security expert or Azure AD specialist to ensure your implementation meets your specific requirements.
