Values from my login view also populate fields in my other views - asp.net-mvc

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

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" }) %>
