Hope you are doing good! Thank you for reaching out. Please find the answer below.

 

1. Enable WebAuthn Redirection:
   • Go to Computer Configuration > Policies > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Device and Resource Redirection.
   • Locate the policy setting "Do not allow WebAuthn redirection".
   • Make sure this policy is set to Disabled or Not configured.
2. Confirm Prerequisites:

• Ensure you have a local Windows device configured with Windows Hello for Business or a compatible FIDO USB security key.
• Your application should be accessing a remote session from a supported platform. Refer to the comparison of Windows App features across platforms for detailed compatibility. 3.Testing Redirection:
• Connect to the remote session using the Windows App or Remote Desktop app.
• Visit a website that uses WebAuthn authentication (like the provided demo link).
• Use an InPrivate window for this test to reduce any potential caching issues.
  • When you’re prompted to authenticate via Windows Hello or your security key, check if the Windows Security prompt appears on your local device; this indicates that WebAuthn redirection is functioning.
