How to disable autocomplete for passwords in IE8 via GPO?
I believe there is a GPO template available from Microsoft for this. Here is a listing of all the GPO settings available for IE8, they do list some entries for disabling Autocomplete under Windows Components\Internet Explorer\Internet Settings\AutoComplete
I can't see any settings listed for just passwords though
