FEITIAN BioPass FIDO2 Series review
A focused hardware-key family for fingerprint-based FIDO authentication.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
FEITIAN BioPass FIDO2 Series is a family of biometric hardware security keys for passwordless authentication and multi-factor login. It is aimed at individuals and organizations that want fingerprint verification alongside FIDO2 or FIDO U2F authentication. The series supports Windows, macOS, and Linux, with USB connectivity across USB-A and USB-C variants. Windows Hello support is also available within Azure AD.
Pricing is structured around two published models. The BioPass FIDO2 Plus Security Key K26+ costs $69 as a one-time purchase and includes fingerprint authentication with USB-C connectivity. The BioPass FIDO2 Pro Security Key K49/K50 costs $126 one time and adds USB connectivity with PIV support alongside fingerprint authentication. This makes the K26+ the lower-cost route for core biometric FIDO authentication, while the K49/K50 is the more suitable choice for deployments that require PIV smart-card functionality.
The management feature set goes beyond sign-in: users can enroll, test, delete, and manage fingerprints; manage PINs; enumerate and delete credentials; and reset the FIDO2 device. PIV is restricted to selected models, and connector choice varies across the series, so buyers should match the specific key to their hardware and authentication requirements. Choose BioPass when on-device fingerprint verification and FIDO standards are central requirements. Organizations seeking those capabilities on Windows, macOS, or Linux can consider the series; buyers who need NFC or PIV on every model should choose a different configuration or product.
