Prepopulate User ID or use default user

Hello,

We want to add RSA authentication to a web application for MFA. The web application should be accessed by same user who is authenticated by RSA. Is it possible that RSA web agent template prepopulates the user ID by detecting currently logged in user on Windows desktop? Browser is Internet Explorer.

Also, there is one template that has only passcode (passcodemanual.htm).  Does this template assume user ID is one that is logged in to Windows? If so, how to use this this template? Currently the template is useridandpasscodemanual.htm

Thanks
