Yubico

It’s often the case that security is an inconvenience and gets in the way of usability and ease of use. There are exceptions though and for a number of weeks I’ve been playing with the Yubikey (thanks to Schack) from Yubico. It’s a small device, which plugs into a USB port, and to the computer acts as a keyboard. It has some advanced security build-in with the ability to generate one-time verifiable passwords, but is incredible easy to use – plug it into the USB port and press the single button when you need to sign in to services supporting the Yubikey.
