Here's my recommendation for a portable password manager
http://sourceforge.net/projects/keepass/
I've been using this for several months and am really satisfied with the passeord generator and level of encryption.
No longer do I feel like I'm using lame passwords easy to crack and I carry it in my thumbdrive so when I go to work I can access persoanl and work related sites without having to remember so many pswrds!
Hope you guys give it a run and see how well it works. I simply installed in in the Corsair (gig) USB drive and it runs like a champ every time.
Also it has room for notes and pesonal additions so it's not just a password keeper but a bit more.
