In my database table there are 2 columns: 1. SaltPassword 2. HashPassword

Below is the HTML code for Login page:

<div class="form-group col-md-12">
   <input id="txtLoginId" runat="server" class="form-control" placeholder="Login ID" />
   <input id="txtPass" runat="server" class="form-control" placeholder="Password" />
                              
   <div class="col-xs-4 col-sm-4 col-md-4">
      <asp:Button ID="btnSave" runat="server" Text="Login" class="btn save" OnClick="btnSave_Click"/>
   </div>
   <div class="col-xs-4 col-sm4-3 col-md-4">
      <asp:Button ID="Button1" runat="server" Text="Forget Password" class="btn save" OnClientClick="window.open('ForgotPassword.aspx', 'ForgotPassword');"/>
   </div>
</div>

Now, when user input password in Password textbox then it should get save into 2 different columns of database as defined above.
