I have exactly the same complaints about my different idine accounts and their different passwords as the original poster to this thread, the reason I stopped in to read it.
As for those auto-password-input things, I used to have one called Gator? When that computer crashed and I was using other peoples computers for awhile, I was forced to try and remember all the old passwords and log in info or use what little info I had written down for accessing important sites during travel.
Since then, I have just forced myself to remember all my logins and passwords by logging in at least a few times a week to all my major sites. It helps on the road so I don't have to have that private info written down, and the concerns that go along with that, and I feel more self reliant. Of course, the smaller sites sometimes take awhile for me to figure out since I don't go there so often. And I have totally given up on trying to figure out my Continental idine account ...
