I love my Yubikey so much that I recently bought another one. I couldn’t find a good use for it yet but I’m sure I will someday :-)

If you don’t know what a Yubikey is, check out its vendor here. Basically it is a one-time password (OTP) generator. It has a USB input device. It doesn’t require batteries to operate so you can use one everywhere without having to worry about such issues. I’m trying to incorporate using it into my daily life so that I can leverage two-factor authentication as much as possible.

Today, I found another usage. Yubikey Wordpress plugin. By using this plugin now I can login to my blog using my password and OTP generated by Yubikey. Yubikey has a web API and the plugin calls the API to authenticate your device.
