Password storage / management software

I would recommend the following:
http://www.fpx.de/fp/Software/Gorilla/

You can create an encrypted password file and then place it on a usb drive to carry your passwords around.

Password Gorilla is also cross platform, ie. Linux AND Windows (and Mac?)

Download the .kit file from the site above, and move to: /usr/bin/gorilla
* Notice I have renamed the file to just 'gorilla'

Now make it executable:
chmod +x /usr/bin/gorilla

Ubuntu users, you will need tclkit:
http://www.equi4.com/pub/tk/downloads.html

Unzip the file:
gzip -d tclkit...

Then move the downloaded file to /usr/bin/tclkit
* Notice I have renamed the file too! (to just tclkit)

Make it executable:
chmod +x /usr/bin/tclkit

Now you should just be able to run: gorilla
