With most people's entire life on the Internet, we find ourselves accessing all our information with a brainful of passwords that tend to fall through the cracks. Not to mention that you really should update your passwords every three months. How do you remember them all, or keep them organized?
I've set up a Microsoft Excel spreadsheet that is password protected. You should be able to find the Protection option under Excel's Tools menu. The spreadsheet holds the login and passwords for all my financial, online auction logins, etc. All you have to do is remember one password.
A few other ideas have been posted on the Simple Living Network.
