YubiKey C FIPS
The YubiKey combines hardware-based authentication and public key cryptography to eliminate account takeovers. Simply insert into a USB slot and authenticate with a touch. YubiKey authentication is four times faster than typing a One Time Passcode and does not require a battery nor network connectivity so it is always on and accessible.
The YubiKey FIPS Series comes in four form factors. Each option includes the same internal components, functionality, and capabilities.
