I cannot see any way in CM for your password to be saved like that. What you can do in CM, is go to your Home tab, then Personal Details, and you can make your profile so that only CM friends can view it. So, now it will be private from your SO.
I think that your operating system, Windows, or whatever you are using, is saving your passwords. I'm not really sure how to tell you to turn this off because it depends on what version of IE you are using. But you can search it in Windows help. Good luck!
Oh, you can always lock your whole computer with a password too, if it is a computer that only you use. I do that because I use my laptop for work.
