The other thing is "cookies" I personally do not use the autocomplete and unless I clear my cookies I am automatically logged in. Cookies also work in conjunction with autocomplete if it is turned on.

It's easy to tell if it is using autocomplete or not. When you go to the login page the username and password are already filled out. If you go to RCU and it just lets you in that is cookies doing that.

To clear your cookies in Internet Explorer.

1. Click on tools and select "Internet Option"
\
Near the middle of the window you will see a button that says "Delete Cookies" just press it.

The next time you login autocomplete will now ask you if you want it to remember your password, just tell it no
