I\'m working on a mature ASP.NET/C# application (it\'s about three years old). For various reasons I\'ve recently begun using the beta IE 11. However, when I first fired u
Yes, IE11 deliberately ignores this attribute on password fields (demo in the 3rd section of this page http://enhanceie.com/test/password/passwordautocomplete.asp).
Password managers encourage strong, unique password creation per site. Unique, strong passwords are difficult to remember and type on touch devices for each site, so users rely on their password manager. IE11 still honors the autocomplete=off attribute on all other AutoComplete input elements (e.g. name, address, credit cards, usernames, phone, etc).

Summarized: When the browser doesn't offer to autocomplete a password, the user assumes that the browser is broken. They then either use another browser which ignores the attribute, or install a password manager plugin that ignores the attribute.
Note: In addition to disabling autocomplete=off, IE11 will also "autofill" the password if certain conditions are met-- see http://msdn.microsoft.com/en-us/library/ie/dn629640(v=vs.85).aspx for details.
