This is because the login session is redirected to the client, thereby making only the client's smart card accessible in the RDP session (WinSCard.dll is replaced in RDP). Microsoft made it this way to for enhanced security reasons **Resolution:** Install TruU on the original source computer (See Use Case 2 below) ### Use Case 2: Source has TruU and RDP Destination has TruU **Result:** TruU Login will fail when the destination attempts to login to the operating system **Explanation:** This is because Microsoft has a security feature where they prevent the use of the certificate (smartcard/FIDO) on the remote host from the Lock Screen, as such use is only available during the active user session **Resolution:** See the guide below: 1. Log into the Workstation using TruU 2. Start the Remote Desktop connection 3. Enter the *name* or *IP address* of the target computer, then click **connect** 4. Select **Start Login with TruU** 5. Provide your *TruU PIN* or biometrics and answer any prompts for RDP 6. After successful authentication, you will see one of the following: 1. Login screen on the target computer 2. Select **Other user** and then select the desired Sign in option 7. Select the **last** smartcard (you will see your login ID on that specific screen) and enter the *TruU PIN* that you used on the source computer 8. You will log in to the computer ### Use Case 3: Source has TruU, but RDP Destination does NOT have TruU **Result:** Fully supported with TruU Login *** [TruU's Internationalization](/docs/truus-internationalization) [How to Determine Whether Agent is using FIDO2 or Cert based login](/docs/how-to-determine-whether-agent-is-using-fido2-or-cert-based-login)
