In the news and helpful hints

SSO provides relief for password headaches (also www.healthcareitnews.com)
SSO, or Single Sign On, is one, long overdue piece that is left out of many network authentication systems. Signing on to multiple information systems (mainframe, PC, etc.) during the course of a day can be mind-boggling, considering security and logging issues in hospital systems.

HINT: Do yourself a favor--rotate your passwords in a scheme you can remember. Don't write them down, but do write down any hints that may help you remember your scheme. If you rotate them regularly, based on your network rules (every 30, 60, 90 days, etc.), it's easier to remember, too. There are some password keeper programs (such as this one from SplashData) you may be able to use on a personal device (i.e. PDA, smartphone). Whatever you do...don't write your passwords down anywhere they can be used to access your account.

Ask your system administrator (if they'll tell you) how many unique passwords you need to have in a year. Many system administrators require xx amount of unique passwords per year or per system. In one of my former lives, our system kept a record of your last 6 passwords; another system only four.
