At work, we use a shared Keepass file (Keepass is a password manager). We are only a small team, so this works out quite well. And this leads us to very secure (and different!) passwords for all our client servers and accounts, because getting and setting passwords is just a click away.

Private, I use a simple system where I have a 'master' password, which I augment with letters and numbers based on the domain name of the service. For example (not my system): A domain has 5 letters and a .com TLD, so I add the number 5 to the end and 'moc.' to the beginning of the master password. You can easily expand this system for your needs. Works really well for me.
