Biometric Security Keys: When Fingerprints Become the Last Shield

In the category of hardware security devices, Biometric USB Dongles (Biometric Keys) are leading the trend in 2025. This solution perfectly combines 'What you have' (physical key) and 'What you are' (user's fingerprint).

The difference lies in On-device Processing:

• Fingerprint data is never sent to the computer or cloud. All matching processes occur within the Secure Element (SE) of the USB itself.
• Even if a hacker steals the key, they cannot activate the authentication function without the owner's fingerprint.

This solution is particularly critical for senior personnel, System Admins, or factory engineers (OT Security) – those who hold access to critical infrastructure. The use of biometric keys is currently recommended by FCT Vinh Thinh as a final 'safety catch' to protect corporate digital identities.
