Use opera, or get a good password manager. Either will be useful in managing your passwords for different sites. I personally don't use IE's save passwords feature do to the many holes in IE.
I'm also a IT services provider besides a web host company and network security is one of my top issues with folks. Don't use common names etc.. Use hardened passwords 7 characters min, upper and lower case, numbers and special characters, use 3 of those 4 and your passwords will be more secure, then if you have a ton of sites that you manage, set your password manager to save your id's and pw's which also encrypts them and you have to log in to the manager which makes it even more secure..
Sorry if that sounds like a pain to you, but if one of your servers is hacked because your passwords aren't strong enough or your system gets compromised I think a little inconvenience is better than the headaches and heartbreaks of a server DOA for a few days.
