K44 names the security-key model. FEIT-IEPASS-K44 is the complete Cisco ordering identifier for that K44 configuration. Use the full code when matching an order, and use K44 when checking the physical key’s connector arrangement and device fit.

The key provides Lightning and USB-C support, allowing connection to Apple-compatible equipment using either physical interface. Operating-system support and authentication application configuration depend on the endpoint and identity environment where the key will be used.

It serves as a physical factor for hardware-based multi-factor authentication. Confirm that the identity platform and target device accept a security key before deployment, then select the Lightning or USB-C connector that matches the device.
