Yubico Launches YubiKey 5 Series, the Industry’s First Multi-Protocol Security Keys Supporting FIDO2

Yubico, the leading provider of hardware authentication security keys, today announced the launch of the YubiKey 5 Series, the industry’s first multi-protocol security keys supporting FIDO2/WebAuthn. With this new addition, the YubiKey 5 series has the capability to replace weak password-based authentication with strong hardware-based authentication.

Yubico continues to create authentication technologies that not only work for today’s authentication scenarios but into tomorrow’s, helping to bridge the gap from existing solutions to a future of password-less login. The YubiKey 5 series delivers the same ease of use, high level of security, and durable construction expected from a YubiKey, with added authentication and communication interface functionality. Multi-protocol in design, including FIDO U2F, smart card (PIV), Yubico OTP, OpenPGP, OATH-TOTP, OATH-HOTP, and Challenge-Response on a single device, the YubiKey 5 series now introduces FIDO2 to the line-up.

The YubiKey 5 NFC is also new to the series, incorporating all protocols support over USB and NFC for new user experiences like tap-and-go authentication across desktop, laptop and mobile with FIDO2. “Innovation is core to all we do, from the launch of the original YubiKey ten years ago, to the concept of one authentication device across multiple services, and today as we are accelerating into the passwordless era,” said StinaEhrensvard, CEO and Founder, Yubico. “The YubiKey 5 series can deliver single-factor, two-factor or multi-factor secure login, supporting many different uses cases on different platforms for different verticals with a variety of authentication scenarios.”

“Passwordless login brings a monumental change to how business users and consumers will securely log in to applications and services,” said Alex Simons, Corporate Vice President for Microsoft Identity Division. “With FIDO2, Microsoft is working to remove the dependency on password-based logins, with support from devices like the YubiKey 5.” The YubiKey 5 series provides superior defence against phishing and account takeovers, enables compliance for strong authentication, and significantly reduces IT costs.
