Adapt a ASP.NET login page to not ask to save passwords (FF & IE)

I have an existing application with a [login to view URL] page which prompts a user for a user ID and password (hidden). At the moment, when the user logs in, FireFox and InternetEXplorer asks to save the password. This is seen as a security risk. I need somebody who can adapt the login page to work in a different way (whatever way works best, jquery, javascript, asp, etc) so that the login is the same look and feel, but FF/IE dies not ask to save the password. Current code segment: <table> <TR> <TD class="Heading"><h4>User code:</h4></TD> <TD class="style2"> <asp:TextBox ToolTip="Enter your usual Windows login ID without the domain or assigned George User Code" CssClass="TextBoxStyle" autocomplete="off" ID="txtUsername" name="foolmeonce" AutoCompleteType="Disabled" runat="server" width="166px" maxlength="20" value=""></asp:TextBox></TD> </TR> <TR> <TD class="Heading"> <h4>Password:</h4></TD> <TD class="style2"> <input type="text" style="display:none;" /> <asp:TextBox AutoCompleteType="Disabled" ToolTip="Enter your usual Windows login password or assigned George Password" CssClass="TextBoxStyle" ID="txtPassword" runat="server" name="foolmetwice" width="166px" maxlength="20" AutoComplete="off" value="" ></asp:TextBox></TD> </TR> <TR> <TD class="ErrorMessage" colspan="2" style="FONT-SIZE: 12pt; FONT-FAMILY: Verdana, Arial,Tahoma"> <asp:Label CssClass="LabelStyle" ID="lblErrorMessage" runat="server" ForeColor="Red" value=""></asp:Label></TD> </TR> </table>
