LayoutTemplate is available in the login control, you can completely change the layout and whatever else you want. Here is a completeled layout designed for a login page that I have used in one project.

 <asp:Login ID="Login1" runat="server">
    <LayoutTemplate>
        <table>
            <tr>
                <td align="right">
                    <asp:Label ID="UserNameLabel" runat="server" AssociatedControlID="UserName">User Name:</asp:Label>
                </td>
                <td>
                    <asp:TextBox ID="UserName" runat="server"></asp:TextBox>
                    <asp:RequiredFieldValidator ID="UserNameRequired" runat="server" ControlToValidate="UserName"
                        ErrorMessage="User Name is required." ToolTip="User Name is required." ValidationGroup="Login1">*</asp:RequiredFieldValidator>
                </td>
            </tr>
            <tr>
                <td align="right">
                    <asp:Label ID="PasswordLabel" runat="server" AssociatedControlID="Password">Password:</asp:Label>
                </td>
                <td>
                    <asp:TextBox ID="Password" runat="server" ></asp:TextBox>
                    <asp:RequiredFieldValidator ID="PasswordRequired" runat="server" ControlToValidate="Password"
                        ErrorMessage="Password is required." ToolTip="Password is required." ValidationGroup="Login1">*</asp:RequiredFieldValidator>
                </td>
            </tr>
            <tr>
                <td align="right">
                    &nbsp;
                </td>
                <td>
                    <asp:CheckBox ID="RememberMe" runat="server" CssClass="hint hide" Text="Remember me next time." />
                </td>
            </tr>
            <tr>
                <td align="center" colspan="2" style="color: Red;">
                    <asp:Literal ID="FailureText" runat="server" EnableViewState="False"></asp:Literal>
                </td>
            </tr>
            <tr>
                <td align="right" colspan="2">
                    <asp:Button ID="LoginButton" runat="server" CommandName="Login" Text="Log In" ValidationGroup="Login1" />
                </td>
            </tr>
        </table>
    </LayoutTemplate>
</asp:Login>

onchange="document.getElementById('password').type = this.checked ? 'text' : 'password'"

Even we can use the onclick event of the checkbox. Refference code

Answer 3

The way I made my show/hide password control incorporated both Muhammad Akhtar's and Kesavarapu Venkatesh's answers. I used the ASP.NET Login control like Muhammad, but also used a checkbox with very similar code like Kesavarapu. The difference between my checkbox and his was the ID the JavaScript is getting, which is "<%=((TextBox)logUsers.FindControl("Password")).ClientID %>" instead of "password", since we are accessing the ASP.NET login control instead of a regular textbox.

<asp:Login ID="logUsers" runat="server" BackColor="#F7F7DE" BorderColor="#CCCC99" BorderStyle="Solid" BorderWidth="1px" FailureText="" Font-Names="Verdana" Font-Size="10pt" OnAuthenticate="logUsers_Authenticate" UserNameRequiredErrorMessage="Username is required.">
    <TitleTextStyle BackColor="#6B696B" Font-Bold="True" ForeColor="White" />
</asp:Login>
<input type="checkbox" onchange="document.getElementById('<%=((TextBox)logUsers.FindControl("Password")).ClientID %>').type = this.checked ? 'text' : 'password'" /> Show password
