I'm not sure what the password thing is all about at that site, but you would have to have an account there for a password to work. And how you go about setting that up, I have no idea. However, if you check out this site:
http://www.jersgirl.com/temps.html , there is a template for a seed packet as well. Just scroll down the page about halfway and the seedpack template is in the middle column.
HTH!
