Whether biometrics is used depends on the site or service you're authenticating with. Fast flashing green LEDs means biometric authentication is in use, but slow pulsing green LEDs mean you can tap with any finger-just like any other non-biometric security key. Two tiny LEDs near the USB-C connector let you know when the device accepts or rejects your fingerprint and when it's requesting biometric authentication. The silver ring is capacitive, like the gold disc on other YubiKeys, and ensures it's being touched by human skin and not accidentally or part of an automated attack. Rubbing it with a piece of metal didn't make a mark, but we'll have to see. Yubico didn't provide any information on the reader's construction, so I'm not sure how well it would hold up on a key ring. Instead of Yubico's trademark circular, gold tap-sensitive disc, the C Bio has a large, black circle with a raised metal frame. Flip it over, and it's starkly different. The C Bio measures just 1.77 by 0.71 by 0.15 inches (45 by 18 by 3.75 millimeters, HWD). MFA-sometimes called two-factor authentication or 2FA-refers to confirming your identity using at least two of a possible three factors: Something you know, like a password something you have, like a security key and something you are, like a fingerprint scan or some other form of biometrics.įrom the back, the C Bio looks nearly identical to the $55 Editors' Choice winner YubiKey 5C NFC: a slim, black rectangle with a USB-C connector at one end and a metal-reinforced keyring at the top. It's missing the advanced authentication features found in other YubiKeys and won't work with an iPhone without a dongle, but it's the best biometric MFA experience we've yet seen-earning it a Technical Excellence award.
While expensive, this small device uses biometric MFA to make it much harder for bad guys to take over your accounts. After being teased several years ago, the company's long-awaited foray into biometric security has finally arrived in the form of the $85 YubiKey C Bio. Yubico has long been the biggest player in the world of security keys for multi-factor authentication (MFA), helping to shape not only the hardware but also the underlying standards on which all such devices rely.
