Protect your Sitecore dev, demo, QA, test website by login page

If you are developing Sitecore projects and for SPRINT demo to client we generally host it publically. Your development, demo, QA or test websites should be access publically but only to handful of people. One simple way is to keep login screen before accessing any page for that session. 

We have to develop this login feature in such a manner that it will be enable disable easily by single setting.

How can we implement this login screen on Sitecore website?

For this we will create some files in Visual Studio and items in Sitecore.

In Visual Studio

In HELIX based project I like to keep login related files in  “Sitecore.Feature.Navigation” feature.

Create one model "UserLogin.cs" in "Sitecore.Feature.Navigation" as

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace Sitecore.Feature.Navigation.Models
    public class UserLogin
        public string UserName { get; set; }
        public string Password { get; set; }

Create one view "SecureLogin.cshtml" in "Sitecore.Feature.Navigation" with below code

@model Sitecore.Feature.Navigation.Models.UserLogin

<!DOCTYPE html>
        body {
            font-family: arial;
            font-size: 14px;

        h1 {
            margin: 0;
            font-size: 20px;
            font-family: arial;
            text-align: center;
            margin-bottom: 22px;

        .loginContainer {
            padding: 31px 28px;
            width: 430px;
            background-color: #7ad;
            border: #ddd solid 1px;
            margin: 100px auto 0;
            border-radius: 10px;
            -moz-border-radius: 10px;
            -webkit-border-radius: 10px;

            .loginContainer label {
                color: #333333;
                float: left;
                line-height: 35px;
                width: 80px;
                clear: both;

            .loginContainer input {
                border: 1px solid #e7e6e6;
                color: #333333;
                float: right;
                line-height: 22px;
                padding: 5px 10px;
                width: 310px;
                margin: 0 0 10px;

                .loginContainer input#BtnLogin {
                    background-color: #ddd;
                    color: #333;
                    cursor: pointer;
                    float: left;
                    font-size: 14px;
                    font-weight: bold;
                    margin-left: 18px;
                    width: 100px;
    <div id="loginWrapper" class="group">

        @using (Html.BeginForm("Login", "SecureLogin", FormMethod.Post))

            <div class="loginContainer">
                <div class="loginLogo"></div>
                <span style="color: #E60000; font-size: 15px;">
                @Html.Label("User Name")
                @Html.TextBoxFor(model => model.UserName)

                @Html.PasswordFor(model => model.Password)

                <input type="submit" title="Login" value="Login" id="BtnLogin" onclick="return checkForNullValues()" class="loginBtn" />

                <div style="clear: both"></div>



    function checkForNullValues() {
        var Username = document.getElementById("UserName").value;
        var Password = document.getElementById("Password").value;
        if (!Username.match(/\S/)) {
            alert("Username can not be blank");
            return false;
        else if (!Password.match(/\S/)) {
            alert("Password can not be blank");
            return false;
        else {
            return true;


    $(document).ready(function () {
        var input = $('.input-validation-error');

        if (input) {
    $(document).ready(function () {
        $('#Password').bind('copy paste cut', function (e) {
            e.preventDefault(); //disable cut,copy,paste

    $(document).ready(function () {
        $("form input[name=UserName]").val("");


Create one controller “SecureLoginController.cs” in “Sitecore.Feature.Navigation” feature as 

using Sitecore.Configuration;
using Sitecore.Feature.Navigation.Models;
using System;
using System.Web.Mvc;

namespace Sitecore.Feature.Navigation.Controllers
    public class SecureLoginController : Controller
        // GET: SecureLogin
        public RedirectResult Login(UserLogin user, FormCollection form)
            return Redirect(GetLoginURL(user, form));

        private string GetLoginURL(UserLogin user, FormCollection form)
            string loginPage = Request.UrlReferrer.ToString();

                if (Settings.GetSetting("SecureLogin.Enable").Equals("True") && user.UserName.ToLower().Equals(Settings.GetSetting("SecureLogin.UserName").ToLower())
                    && user.Password.Equals(Settings.GetSetting("SecureLogin.Password")))
                    loginPage = Request.Url.Scheme + "://" + Request.Url.Authority + form["requestedurl"];
                    Session[Settings.GetSetting("SecureLogin.SessionName")] = "True";
                    Session.Timeout = 30;
            catch (Exception exception)
                Sitecore.Diagnostics.Log.Error("NavigationController > Initialize Exception", exception, this);
            return loginPage;

Create a config “Feature.Navigation.config” at “App_Config\Include\Feature” location to get value of different keys. You can create these values in Sitecore dictionary as well, but I like to create them in config file. Below keys names are self-explanatory as

<configuration xmlns:patch="" xmlns:set="">
            <setting name="SecureLogin.Enable" value="True" />
            <setting name="SecureLogin.UserName" value="steve" />
            <setting name="SecureLogin.Password" value="jobs" />
            <setting name="SecureLogin.SessionName" value="Success" />
            <setting name="SecureLogin.RedirectPage" value="/securelogin" />

Check this session is exist for every request. Best place to check this is header or footer as they are part of every page. I am placing session check code in “PrimaryMenu()” action method in “NavigationController.cs” file as

public ActionResult PrimaryMenu()
      if (Settings.GetSetting("SecureLogin.Enable").Equals("True"))
           string sessionKey = Settings.GetSetting("SecureLogin.SessionName");

           if (Session[sessionKey] == null || (Session[sessionKey] != null && !System.Convert.ToString(Session[sessionKey]).Equals("True")))

       var items = this.navigationRepository.GetPrimaryMenu();
       return this.View("PrimaryMenu", items);

In Sitecore

Create one Model item at “/sitecore/layout/Models/Feature/Navigation/LoginUser” and set Model Type value as "Sitecore.Feature.Navigation.Models.UserLogin, Sitecore.Feature.Navigation"

sitecore login model
Sitecore Login Model

Create one layout item at “/sitecore/layout/Layouts/Feature/Navigation/SecureLogin”. Set Path for view as "/Views/Navigation/SecureLogin.cshtml" and insert link for above model as "/sitecore/layout/Models/Feature/Navigation/LoginUser"

Sitecore Login Layout
Sitecore Login Layout

Create “SecureLogin” item under Home item with any page template. Keep its icon as "Network/16x16/key1.png" to identify easily in content tree and assign above layout in its Final Layout as

Sitecore Login Final Layout
Sitecore Login Final Layout
That’s it!!!

Now whenever any visitor tries to access public page, he must have to authenticate via login screen.

Login Screen

One last thing, while going LIVE, we must remove this login screen by disabling it through “Feature.Navigation.config” file with below key settings as

<setting name="SecureLogin.Enable" value="False" />
