Insert the FEITIAN K26 USB-C Security Key into an available USB-C port on your computer or compatible device. The device is designed for plug-and-play functionality on most supported operating systems.

2.2 Fingerprint Enrollment

To utilize the biometric authentication feature, you must enroll your fingerprints. The fingerprint registering application can be downloaded from Feitian's Official Website. Follow the on-screen instructions within the application to register your fingerprints securely.
