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+.
