Computer login with two-factor authentication
It doesn’t matter which operating system you have installed — Windows, Mac OS X or Linux — you can use a YubiKey to strengthen authentication and keep intruders from prying into your computer.
Associating a YubiKey with a Windows account is straightforward for both enterprise users connected to a domain and individuals running a single computer.
YubiKey two-factor authentication can be activated in the Challenge-Response mode on OS X.
The Yubico Pluggable Authentication Module (PAM) provides an easy way to integrate the YubiKey into existing user authentication infrastructures.
The YubiKey NEO supports the Personal Identity Verification (PIV) interface and performs RSA or ECC sign/decrypt operations using a private key stored on the smart card, through common interfaces such as PKCS#11.
