How to add SSO, MFA, and Passwordless authentication to your .NET app

Authentication is a crucial feature in application development, and WorkOS simplifies the integration of modern authentication methods like Single Sign-On (SSO), Multi-Factor Authentication (MFA), and Passwordless login for .NET applications. This tutorial guides developers through implementing these authentication strategies using WorkOS SDKs and APIs, allowing them to choose the method that best suits their product needs, such as SSO for enterprise clients or Passwordless for lightweight apps. It outlines the process of setting up SSO by creating authorization endpoints and handling callbacks, adding MFA through TOTP or SMS codes for enhanced security, and enabling Passwordless login using one-time codes sent via email. The tutorial also covers the prerequisites and steps for installing the WorkOS .NET SDK and securing API keys. By incorporating these authentication methods, developers can build applications with scalable, enterprise-ready authentication flows. Additionally, WorkOS offers advanced capabilities such as Directory Sync, Admin Portal, Roles and Permissions, and Audit Logs to further enhance security and facilitate enterprise adoption.
