Is the task of trying to keep track of all your passwords got you in a bind. Try installing LastPass with Internet Explorer, Firefox, Chrome, and Safari. Then when you save a password when using your office computer with Internet Explorer or Firefox, it is available on your home Mac using Safari. The process is much safer than writing down passwords or trying to remember what password you used on which site. It is also more secure than using the built-in password managers it the various browsers.
