Microsoft posted some new details this week on how Internet Explorer 11 will allow users to share the same website passwords when using the browser on Windows 8.1 and Windows Phone 8.1



From WPCentral:

IE11 also automatically pre-populates username and password credentials after a secure web page has loaded. For people who are still a bit paranoid, IE11 still prompts the user to save passwords even if the autocomplete=off attribute is set on the website.
