Yubico’s first biometric authentication security key YubiKey Bio Series is now available for purchase. YubiKey Bio reinforces the YubiKey design by storing the biometric fingerprint material in a separate element to enhance the physical security of the key.

Secure and reliable, YubiKeys are known for their high durability and sole focus on security. The YubiKey Bio Series is yet another step toward creating the perfect security key for protecting user accounts.

How Does YubiKey Bio Series Work As Second Step In MFA?

YubiKey Bio is widely advertised as a go-to device for passwordless logins. YubiKey Bio can be also used as a second step during Multi-Factor Authentication (MFA). An important security feature of YubiKey Bio that we rarely see mentioned on the web is that it combines the Possession Factor (what you have) with the Inherence Factor (who you are) to create a very secure method of verifying user identities. MFA that uses YubiKey Bio covers one authentication factor (Knowledge) during the first step of authentication and two factors (Possession & Inherence) in the second step. All in all, MFA with YubiKey Bio allows for a very secure three-factor authentication.

Refer to the following login flow of MFA with YubiKey Bio Series:

During the YubiKey Bio authentication, the biometric fingerprint material never leaves the key, which eliminates the anxiety concerning the security of fingerprints stored in an external database. It is virtually impossible to compromise the key without having physical access to it. Should the malicious party take physical possession of the key, the key will require providing a PIN after 3 failed biometric attempts. Thanks to storing the biometric fingerprint material in a separate well-secured element, YubiKey Bio is resistant to physical attacks based on tampering with the hardware elements of the key.
