Technically, MultiKey is a filter driver. It sits between the operating system's USB stack and the application requesting the dongle. When the application sends a request to the USB port looking for a security key, MultiKey intercepts that request and returns the appropriate response from its virtual storage.
Because Multikey operates at the kernel level to emulate hardware, modern Windows systems require drivers to be digitally signed by Microsoft. Because older versions of Multikey lack these modern, valid cryptographic signatures, users often encounter installation roadblocks. This has necessitated workarounds, such as permanently disabling or utilizing third-party driver signature tools to force the driver installation. Typical Use Cases in CAD/CAM Environments
