The YubiKey Bio works across platforms including Windows, macOS, Chrome OS and Linux. For mobile devices requiring NFC, we recommend using the YubiKey 5 NFC or YubiKey 5C NFC,' says Yubico's APJ director solution engineering, Alex Wilson. 'Use cases are for authentication to services on shared workstations and mobile restricted environments The YubiKey Bio can be used wherever FIDO2 or FIDO U2F authentication is available. While The YubiKey Bio works perfectly well for home consumers who want to add a hardware-based authentication method to their social account logins, it's clear that the YubiKey Bio is geared more towards business users and cloud-first or desktop login environments, particularly as it “works out-of-the-box with Citrix Workspace, Duo, GitHub, IBM Security Verify, Microsoft Azure Active Directory and Microsoft 365, Okta and Ping Identity.”

Basically, the YubiKey can work for authentication across any service that supports FIDO2/WebAuthn/U2F. It is supported by Google Chrome, Microsoft Edge, and Mozilla Firefox.

WebAuthn is a browser API that supports secure user authentication. The YubiKey Bio supports “biometric login on desktop with all applications and services that support FIDO2/WebAuthn/U2F”.Ī quick rundown of those acronyms: FIDO2 is a framework that aims to move the world beyond passwords to other methods of authentication, like two-factor authentication (2FA), tokens, biometrics, to name a few. Available in USB-C and USB-A, and it also has a hole so you can store it on a keyring or lanyard if preferred. There is a round fingerprint sensor in the middle of the device, otherwise, the design is unassuming and understated.

The YubiKey Bio measures just 4cm long and 1.3cm wide and looks similar to a standard USB stick. Since then, Yubico has produced many iterations of the YubiKey, including one of the most recent products, the YubiKey Bio. Its purpose was to offer a portable authentication key that works across different services. In 2007, Swedish company Yubico launched the YubiKey 1.0, a one-time password hardware key.
