How to use U2F FIDO security key for Microsoft Remote Desktop MFA access

Rohos Logon Key allows using FIDO U2F keys to protect Terminal Server with the strongest MFA method.

How to setup Rohos on client PC:
  • Download Rohos Logon Key Compact setup file download>>
  • Install with command line – rohos_logon_compact.exe /VERYSILENT /usbdev=rohos_u2f.dll 

Rohos Logon Key Compact installs a plugin component for  MS Remote Desktop Connection application. This component uses RDP Virtual Channels to allow U2F challenge response authentication with Rohos on remote server. This component is required since RemoteFX functionality does not work while Remote Session has Windows Logon screen. 

How to setup Rohos Logon Key on Terminal Server:

First, you need to setup RemoteFX device redirection on your Local PC and Terminal Server, use this guide>. As an alternative you may also attach U2F keys directly to Windows Server if your virtualization solution allows it.

  • Connect to TS with redirected U2F key.
  • Install Rohos Logon Key
  • Open Setup Key, and choose U2F Security Key as MFA device type, choose user and click Setup Key.
  • Open Options and choose MFA policy “For Remote Desktop Users”, setup Emergency Login.

MFA setup is done!

Now you can use U2F Key for MFA login into a previously configured user account. NLA password is used by the underlying authentication system to let you into the Remote Login screen, and then Rohos Logon Key applies 2FA control by performing a Challenge-Response communication with remote U2F key. The remote key provides a unique digital signature as a response, Rohos on the TS side grants or rejects remote desktop access upon verifying the signature.
