I found this blog entry to be useful. If you link back to it, you will find a comment I made about how to save your authorized_keys to a flash drive so you don’t have to fiddle with username/password at work but to take your laptop home, you may want to disable that “auto logon” feature of using a public/private key and use username/password instead.
Have a look:
And if you have any questions about how to use a flash drive to store your ssh keys, leave me a post and I’ll post the detailed instructions in the comments.
