Values from my login view also populate fields in my other views

Question

When I login I enter my user name and password. On a different create view these values also populate the email address and the password fields. Why is this, and what can I do to stop it?

The next 2 markups are my login view and my create view

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<ITOC.WebUI.Models.LogOnModel>" %>

Answer 1

This is probably due to a browser autocompletion feature. You could append the non standard autocomplete="off" to your input fields:

<%: Html.TextBoxFor(model => model.User.Forename, new { autocomplete = "off" }) %>
