Recently Chrome and Chrome OS implemented support for security keys with two factor authorization. Yesterday I received my +Yubico from Amazon and was left with that now what feeling. +James Welbes was nice enough to point me in the right direction. This post and video will hopefully demonstrate how simple two factor can be with Yubico.
The Yubico will not be too useful on your registered trusted computers, but when you are using a shared or public computer it can be a life saver. After you put in your password, you simply insert your Yubico security key to finsh the log on process.
