Lockdown Browser is a specialized web browser created by Respondus, a company focused on educational testing software. Unlike Chrome, Firefox, or Safari, this browser serves one specific purpose: it restricts what students can do on their computers during online exams and quizzes. When you open Lockdown Browser to take a test, the software locks down your device so you cannot switch between applications, access other websites, or use features like copy-paste or right-click menus.

Schools and universities adopted this tool because academic integrity matters. When courses moved online—especially after 2020—instructors faced a challenge: how do you prevent cheating on exams when students aren't in a physical classroom? Lockdown Browser became one answer. According to Respondus' own reports, the tool is used at over 3,000 institutions worldwide. That includes community colleges, four-year universities, and some high schools running virtual or hybrid programs.
The browser works by creating what's essentially a testing "sandbox." Once you launch an exam through Lockdown Browser, your computer enters a locked state. You cannot minimize the browser window, open new tabs, or access your file system. The camera can be activated to monitor your testing environment (though this depends on what your school's course setup requires). When your exam time ends, the browser unlocks and returns your computer to normal operation.
Understanding how Lockdown Browser functions helps you prepare for using it in your courses. If your instructor has assigned an exam through this platform, knowing what to expect removes confusion on test day. The tool itself does not decide whether you pass or fail—your answers do. Lockdown Browser simply prevents external resources from influencing your test performance.
Practical Takeaway: Before you encounter Lockdown Browser in a course, understand that it's a testing tool designed to create fair exam conditions. It's not punitive software—it's simply how your school levels the playing field when assessments happen online.
Getting Lockdown Browser onto your computer requires visiting the official Respondus website. Go to respondus.com and look for the section labeled "Lockdown Browser." From there, you'll find a link to the browser's landing page, where you can retrieve the installer file for your operating system. Respondus offers versions for Windows and Mac computers. Mobile devices have a separate app available through the Apple App Store or Google Play Store, though full-featured exam proctoring on phones and tablets has limitations.

The actual retrieval process involves downloading an installer file, which is a small program that sets up Lockdown Browser on your system. On Windows, the file typically appears in your Downloads folder with a name like "LockdownBrowser-Setup.exe." On Mac, you'll see something similar with a ".dmg" extension. The file size is relatively small—usually between 30 and 80 megabytes—so it won't consume much of your storage or take hours to retrieve even on a moderate internet connection.
Once you have the installer file, opening it launches a setup wizard. This wizard walks you through installation steps: you choose where to install the program (usually the default location is fine), accept the terms of service, and confirm that you want to proceed. The entire installation typically takes less than five minutes. When it completes, you'll see a Lockdown Browser icon on your desktop or in your applications menu, depending on whether you use Windows or Mac.
No account creation is required to retrieve or install Lockdown Browser itself. However, when you actually launch an exam through the browser, you'll need to enter credentials—usually your school email and password, or whatever login system your institution uses. This is how your school's learning management system (like Canvas, Blackboard, or D2L) recognizes that it's you taking the test.
One important note: Lockdown Browser is genuinely free. Respondus does not charge students for the software. Your school may have purchased site licenses, meaning the institution covers any costs. You should never pay money to access Lockdown Browser as a student.
Practical Takeaway: Visit respondus.com to find the correct installer for your computer type, run the installation wizard, and give it a few minutes to set up. Save the installer file somewhere you can find it again in case you need to reinstall later.
Before you retrieve Lockdown Browser, verify that your computer meets the system requirements. Respondus publishes these specifications on their website, and checking them prevents wasted time on installation attempts that will ultimately fail. For Windows computers, you need Windows 10 or Windows 11. For Mac users, the requirement is macOS 10.14 or newer. If you're running an older version of either operating system, you may not be able to use Lockdown Browser, and you should contact your school's IT department for guidance.

Your computer also needs a reasonable amount of available storage—at least 100 megabytes of free space beyond what the installer itself requires. This is rarely a problem for modern devices, but if you're working with a very old laptop or a device that's nearly full, clearing some space beforehand is wise.
Internet connection quality matters more than you might think. Lockdown Browser communicates with Respondus' servers during exam launch and submission. A weak or unstable Wi-Fi connection could cause problems when you're taking a test. Many students using Lockdown Browser take this opportunity to reconnect to their home network with a strong signal, or they use a wired Ethernet connection if their computer has that capability. If your internet is unreliable, test it ahead of time by opening a web browser and checking your connection speed (sites like speedtest.net provide this for free).
Antivirus software and firewalls occasionally conflict with Lockdown Browser. This is relatively rare, but if your computer runs security software that you installed yourself (rather than the built-in Windows Defender or macOS security features), you may want to verify that Lockdown Browser isn't being blocked. You can test this by attempting to launch it before your actual exam date. Your school's IT support can help if conflicts arise.
Chromebooks and tablets present special cases. Most Chromebooks cannot run the full desktop version of Lockdown Browser, so check with your school if you rely on a Chromebook. Tablets and phones can use the Lockdown Browser app, but certain proctoring features may not function the same way as they do on computers.
Practical Takeaway: Check whether your device meets the Windows 10+ or macOS 10.14+ requirements, ensure you have a stable internet connection, and test the browser launch before your exam date so surprises don't occur when it counts.
Once you've confirmed your computer's compatibility and have the installer file, the installation process follows a straightforward sequence. First, locate the installer file in your Downloads folder and double-click it. This action launches the setup wizard—a window that guides you through the installation. On Windows, you might see a security prompt asking if you want to allow this program to make changes to your device. Click "Yes" to proceed.

The setup wizard typically presents several screens. The first screen usually displays the software license agreement. You'll need to read through it (or at least acknowledge that it exists) and click a button confirming you accept the terms. These agreements are lengthy, but they contain important information about how Respondus uses data and what the software is designed to do. Taking 30 seconds to skim the key points is worthwhile.
Next, the wizard asks where you want to install Lockdown Browser. The default location—usually "C:\Program Files" on Windows or "Applications" on Mac—works for almost everyone. Unless you have a specific reason to change the installation location, click the option to use the default path and move forward.
After selecting the installation location, the wizard begins copying files to your computer. A progress bar shows how much of the installation remains. This step usually takes one to three minutes. During this time, avoid interrupting the process or putting your computer to sleep.
Once the files finish copying, the wizard may offer to create a desktop shortcut. Clicking "Yes" here is convenient—it places a Lockdown Browser icon directly on your desktop, making it easy to find later. If you decline, the program still installs; you'll just need to find it in your applications menu when you need to use it.
