Multi Tabs should be restricted at browser. Add a client side code using JS. // Check if the current page is the first instance if (sessionStorage.getItem('isFirstInstance') === null) { // Set a flag in sessionStorage to identify the first instance sessionStorage.setItem('isFirstInstance', 'true'); } else { // If not the first instance, redirect to another page or display a message alert('Multiple tabs are not allowed. Closing this tab.'); window.open('', '_self').close(); } If you want to redirect users to a specific page when they open multiple tabs, you can do this on the server side. It can be done by using the following code. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load ' Check if the current page is the first instance If Session("isFirstInstance") Is Nothing Then ' Set a flag in the session to identify the first instance Session("isFirstInstance") = True Else ' If not the first instance, redirect to another page Response.Redirect("MultipleTabsNotAllowed.aspx") End If End Sub Inspect Console should be restricted at entire application. It's not possible to completely prevent users from accessing the browser's developer tools or inspecting the console because these tools are integral parts of web browsers and are intended for developers to debug and analyze web pages. However, you can make it more difficult for users to access these tools or receive a notification when they open the console. Keep in mind that determined users may still find ways to bypass these measures. Console Detection Add the following JavaScript code to detect when the console is opened and display a message in the console: // Check if the console is open function detectDevTools() { if (window.console && window.console.firebug) { console.clear(); console.log("Hey, curious developer! This is a restricted area."); } } // Set an interval to continuously check for console opening setInterval(detectDevTools, 1000); Right Clicks should be restricted at entire application. For disabling the right click context menu, which includes the option to open the developer tools. Add the following JavaScript code in the section of your HTML file: document.addEventListener('contextmenu', function (e) { e.preventDefault(); }); Copy Paste should be restricted at entire application. Can be done using the following JavaScript :- document.addEventListener('copy', function (e) { e.preventDefault(); alert("Copying is not allowed."); }); document.addEventListener('cut', function (e) { e.preventDefault(); alert("Cutting is not allowed."); }); document.addEventListener('paste', function (e) { e.preventDefault(); alert("Pasting is not allowed."); }); Back & Forward buttons should be disabled of browser. User login in their own account. And user clicks on Back & Forward button of browser It is not recommended, as it interferes with the standard navigation behavior and can create a poor user experience. Users expect to have control over their navigation, and disabling these buttons may lead to frustration and confusion. But you can able to achieve this by following JS code. history.pushState(null, null, document.URL); window.addEventListener('popstate', function () { history.pushState(null, null, document.URL); }); Please accept the answer if you find the same is useful!
