Strong Passwords

I was talking to a co-worker the other day about strong passwords.  It was a big focus on my pervious talk at SoftwareGR and I wanted to get his thoughts on the issue.  He recommended YubiKey by Yubico.  It's a small hardware stick that plugs into your usb.  After you type your typical password, such as 'qwerty', you push the button on the stick and it inserts a series of characters assigned to that chip.  So your password will now look like:  'qwertyE&5%J9*3~!aFfT'.  You can then rely on your memorable weak password and the strength of the YubiKey to create a strong password.  It looked very simple and extremely secure.  I am going to get this chip and try it out for myself.
