I’ve bought 2 Yubikeys several months ago and didn’t really took the time to play with them.

A ex-colleague took that time and configured it on his desktop under ArchLinux. I decided to play with it, see how could it works and with his help, put it in place in a very short time.

I configured it to work in parallel of my password. With that configuration, I do not need anymore typing my password, but only need to plug in my Yubikey. If I loose it, I can enter the password instead.

And if I remove it, it automatically launch my screensaver with locking feature.

Pretty cool no ? If you do not have a Yubikey, you can order one there. If you have one and want to see how I configured it, follow the link.
