And yet they recently changed it so that if you name a text field username or password it will get filled in with the current user's info, even when it is an admin page where you create new users. There is no way to instruct Chrome to NOT autofill your credentials onto another user. They removed support for the HTML attributes ages ago and even removed the workaround (hidden fields with display: none that don't get used) developers used to prevent this behavior.
