When a web application is secured by the DualShield IIS Agent with MFA, the agent adds an extra layer of authentication process over the web applicationsapplication's own form-based authentication. Without the Single-Sign-On or Auto Logon, users will be firstly authenticated by both the DualShield SSO, then by the web application's orginal logon original login process which is usually the user's AD credential verification.

- Configure DualShield SSO to verifiy verify the 2nd factor only, e.g. one-time-password etc, and keep the application's orginal logon original login process which will verify the user's AD credentials. In this option. you do not need to enable Single Sign-On or Auto Logon.
- Configure DualShield SSO to verifiy verify both the 2nd factor and the 1st factor. In this option. you will need to enable Single Sign-On or Auto Logon.
