Windows Server 2012 asking for Other User and Passcode when accessing via Remote Desktop

  • 772

We recently noticed a change in the login process on one of our Windows 2012 Servers. When we go to login it now prompts us for "Other User"

Windows Server 2012 Passcode Other User

After which it then prompts for a User Name, Password, and Passcode

Windows Server 2012 User name Password Passcode

I have never seen the request for a Passcode when logging to a windows server before. I am able to login using my standard username and password (leaving the Passcode blank) but I am curious why it is asking for a passcode. Also it prevents my Remote Desktop Manager software from using automatic login.

Is there any way to disable the Passcode request at login? We aren't seeing this on a 2012 R2 server in the same datacenter, and nobody I have talked to knows anything about it. I don't see any recent updates that look like they could have changed the authentication process, and an online search doesn't show any results.

    Following the advice of David and Brad I checked group policy using gpresult /v and found a policy called Multi-Factor-Authentication-ADMINS, which appears to be setting some registry keys in SOFTWARE\Policies\PassGo Technologies\Defender\Defender GINA.

    It appears to be a product called Quest Defender (now owned by Dell Software), and there is an entry in the Control Panel Add-Remove programs section called Defender Desktop Login

    So it appears we have a new two factor authentication system. I'll check with our IT department and report back if I find a way to remove it.
