YubiKey - tiny OTP authentication token

This is a great new OTP authentication token - a tiny USB device that emulates a USB keyboard and generates a long, complex OTP each time you need it.

It seems to have multiple benefits over traditional OTP tokens that use an LCD screen:

• very small
• no battery
• generates much longer OTPs

Because it emulates a USB keyboard, it will work in most computers regardless of operating system (i.e. it does not require any special driver to be loaded). It should also be incredibly cheap, being so simple. Read more about the technology here.
