Multi-protocol security key secures modern and legacy systems
The YubiKey supports WebAuthn/FIDO2FIDO U2Fone-time password (OTP)OpenPGP 3and smart card authentication offering a solution that bridges legacy and modern applications. Yubico and the YubiKey will continue to grow with your evolving business needs.
The YubiKey supports one-time passcodes (OTP)
OTP supports protocols where a single use code is entered to provide authentication. These protocols tend to be older and more widely supported in legacy applications. The YubiKey communicates via the HID keyboard interfacesending output as a series of keystrokes. This means OTP protocols can work across all OSs and environments that support USB keyboardsas well as with any app that can accept keyboard input.
The YubiKey enables smart card authentication
Smart cards are another supported protocol on the YubiKey. The YubiKey identifies itself as a smart card reader with a smart card plugged in so it will work with most common smart card drivers. The YubiKey allows three different protocols to be used simultaneously – PIVas defined by the NIST standard for authentication; OpenPGP for encryptiondecryptionand signing; and OATHfor client apps like Yubico Authenticator.
Enable modern authentication with FIDO U2F
FIDO U2F is another protocol supported by the YubiKey. The U2F protocol provides strong authentication without requiring a complex backend or framework to support it. Turning traditional authentication on its headFIDO U2F makes the authentication devicelike the YubiKeythe authentication provider. It issues unique keys to the services it is authenticating againstensures each service does not have any information about the othersand removes the need for a central authentication service.
Experience passwordless authentication with FIDO2
FIDO2 is the passwordless evolution of FIDO U2F. The overall objective for FIDO2 is to provide an extended set of functionality to cover additional use caseswith the main driver being passwordless login flows. The U2F model is still the basis for FIDO2 and compatibility for existing U2F deployments is provided in the FIDO2 specs.
