Yubikey : Configure your yubikey with pam
Local Authentication Using Challenge Response
The PAM module can utilize the HMAC-SHA1 Challenge-Response mode found in YubiKeys starting with version 2.2 for offline authentication. This mode is useful if you don’t have a stable network connection to the YubiCloud.

The yubikey is a small device that act as a token generator for authentication system. Yubico build them and, as they're seen as a Universal Keyboard, they can be easily interfaced with any kind of system.
From generating OATH token, to One Time Password systems, going by Radius and OpenVPN server authentication, they can be used for a lot of funny things and, among other thing, it's free software (not free hardware, alas). The token is at $25 and you can order them by huge quantities.
Simply put, it's a good token for it's price and, given my threat model (my computer being stolen) it is enough.
