MFA for Windows Credential Provider

The Okta Credential Provider for Windows enables strong authentication using MFA with Remote Desktop Protocol (RDP) clients. Using the Okta Credential Provider for Windows, RDP clients (Windows workstations and servers) are prompted for MFA when accessing supported domain joined Windows machines and servers.

Before you begin

Requirements for installing the Okta Credential Provider for Windows:

  • Proxy Configuration: The Okta Credential Provider for Windows does not support a discrete proxy configuration but will obey system level proxy configurations. To understand management of proxies on Windows machines, refer to docs.microsoft.com.
  • The Windows machine used for installation must have an active internet connection with port 443 open.
  • The installing account must have administrative rights to install the Okta Windows Credential Provider Agent, Visual C++ Redistributable and .NET 4.0+.
  • Inline enrollment is not supported. End users can't enroll an authenticator during an RDP sign in. End users must have enrolled their MFA authenticators previously. End users without an enrolled authenticator receive an authentication failed response from Okta when attempting to sign into a Windows server using RDP.

Limitations

Please note the following limitations:

  • Only a single Okta Verify device should be enrolled. Enrolling second and subsequent Okta Verify devices may cause undefined or unexpected behavior.
  • When defining password policy rules, if Any enrolled authenticator used for MFA/SSO is selected for Additional verification, RDP password is disabled and no longer functions.
  • TLS 1.2 is required. For information on enabling TLS 1.2 in .NET and in Microsoft Internet Explorer browsers, see Okta ends browser support for TLS 1.1.
