What Lockdown Browser Is and How It Works
Lockdown Browser is a specialized web browser created by Respondus, a company that develops educational testing software. Unlike standard web browsers like Chrome or Firefox, Lockdown Browser restricts what students can do on their computers during online exams and assessments. Educational institutions use this tool to maintain test integrity by preventing cheating during proctored exams.

The browser functions by taking control of your computer during a test session. Once you launch Lockdown Browser and enter an exam, the software locks down your device's operating system. This means you cannot access other programs, switch to different windows, or use keyboard shortcuts that might allow you to look up answers or communicate with others. The browser prevents access to the clipboard, disables right-click menus, and blocks printing functions.
Lockdown Browser works with learning management systems (LMS) that schools and universities use, such as Canvas, Blackboard, Moodle, and D2L. When your instructor creates an exam in one of these systems and designates it to require Lockdown Browser, students must use this specialized browser to access the test. The software is available for both Windows and Mac computers, though specific system requirements must be met for it to function properly.
The monitoring features built into Lockdown Browser serve two purposes: they prevent unauthorized access to external resources during the test, and they create a record of the testing session. Schools use this information to verify that exams were taken under controlled conditions. According to Respondus' own documentation, the software has been used by institutions worldwide to administer millions of exams annually.
Practical takeaway: Before taking any exam that requires Lockdown Browser, test your computer to ensure it meets the technical requirements. Visit your school's IT support website to find system requirements specific to your institution, as these can vary based on how your school configures the software.
Core Monitoring Capabilities and What Gets Recorded
Lockdown Browser monitors several categories of user activity during a testing session. Understanding what the software tracks can help you prepare for exams and know what to expect. The browser records metadata about your testing session, including the time you started and ended the exam, how long you spent on each question, and whether you submitted answers on time.

The software captures keyboard and mouse activity throughout the test. This includes tracking whether you pressed specific key combinations, how many times you moved your mouse, and which parts of the screen received the most attention. While Lockdown Browser does not record video of your face or your physical surroundings by default, it does monitor your interactions with the exam interface itself. Some institutions combine Lockdown Browser with additional webcam monitoring tools, but this requires separate configuration and student notification.
One significant monitoring feature is tab and window detection. If you attempt to open another browser tab, switch to a different application, or minimize the browser window, Lockdown Browser records these attempts. The software logs the time, duration, and nature of any deviation from the active exam window. According to research from Indiana University and other institutions, these flags are among the most commonly reviewed data points when instructors investigate potential academic integrity concerns.
The browser also monitors network activity to some degree. It can detect when applications attempt to access the internet or when your computer tries to connect to external devices. Lockdown Browser prevents connections to other computers on your network, though it maintains your connection to the testing server. This prevents students from accessing shared files or receiving information from other devices.
Additionally, the software flags instances where students copy or paste content, attempt to use browser developer tools, or try to take screenshots. The browser records whether you accessed the browser's back and forward buttons or tried to reload the page. All of these activities create a detailed log that instructors can review after the exam concludes.
Practical takeaway: Review the specific monitoring features your school uses before your exam. Ask your instructor or academic integrity office which particular activities are flagged as violations, since policies vary by institution. Some schools focus only on major deterrents like tab-switching, while others monitor all recorded activities closely.
Technical Requirements and System Specifications
Lockdown Browser functions only on computers that meet certain hardware and software specifications. These requirements exist because the monitoring features demand significant system resources and direct access to operating system functions. Before you can use Lockdown Browser, your computer must run a compatible operating system version.

For Windows computers, Lockdown Browser typically requires Windows 10 or later. For Mac computers, the software usually needs macOS 10.13 (High Sierra) or newer. However, specific versions can change as software updates occur. Your institution may have different requirements based on their configuration, so checking with your school's IT department provides the most accurate information for your situation.
The software requires adequate processing power and RAM to function smoothly. Educational technology organizations recommend at least 4 GB of RAM, though 8 GB provides more reliable performance. Older computers or those running resource-intensive programs alongside Lockdown Browser may experience slowdowns during exams. Some institutions have published specific laptop recommendations for students, identifying which computer models work best with their deployment.
Internet connectivity is essential for Lockdown Browser to function. You need a stable, continuous connection to the internet because the browser must communicate with your school's testing servers throughout the exam. A connection loss during an exam can cause significant problems. Many institutions recommend that students take exams on a wired internet connection rather than WiFi to ensure stability, though this is not always possible.
Lockdown Browser does not function on smartphones, tablets, or Chromebooks. These devices use different operating systems that the software does not support. If your school requires Lockdown Browser, you must use a traditional desktop computer or laptop running Windows or macOS.
Some security software, virtual machines, and network configurations can interfere with Lockdown Browser's operation. Antivirus programs, firewalls, and VPN software may block the browser's ability to monitor your system or communicate with testing servers. Your IT department can provide guidance on configuring your security software to allow Lockdown Browser to function properly.
Practical takeaway: Run the Lockdown Browser system checker tool several days before your exam to verify your computer meets all requirements. This tool is typically available on your school's testing portal and provides specific feedback about any compatibility issues. If problems exist, contact your IT department with enough time to resolve them before your test date.
Privacy Considerations and Data Protection
Understanding how your data is handled during Lockdown Browser testing provides important context about privacy and security. Schools collect monitoring data specifically to verify exam conditions and investigate potential academic integrity violations. This data typically includes logs of your activity during the testing window, but institutional policies govern how long this data is retained and who can access it.

The monitoring records created by Lockdown Browser are stored on your school's servers, not with Respondus directly. Your institution controls the security of this data and determines access permissions. Most universities have data retention policies specifying how long testing records are maintained—commonly ranging from one to seven years depending on the institution's practices and legal requirements. After this retention period, data is typically deleted or anonymized.
Students generally do not have automatic access to the detailed monitoring logs generated during their exams. However, if you believe monitoring data was used inappropriately in an academic integrity investigation, most institutions have formal processes for requesting records. Your student rights office or dean of students can explain your school's specific procedures for accessing this information and disputing findings based on monitoring data.
Lockdown Browser monitoring data can potentially be used in academic integrity proceedings if an instructor suspects cheating. The flagged activities—such as multiple attempts to switch windows or evidence of external resource access—may be presented as evidence. However, schools cannot rely solely on monitoring data to prove violations. Academic integrity policies across most institutions require investigation and the opportunity for students to provide explanations for flagged activities.
Technical limitations in monitoring mean that some activities cannot be definitively detected. For example, Lockdown Browser cannot detect if someone outside your computer's view is reading answers to you verbally, since it does not record audio. This is why many institutions combine Lockdown Browser with live proctoring or recorded webcam sessions for high-stakes exams. The combination of technical and human monitoring creates a more comprehensive approach to test security.
Your school's privacy policy should explain how monitoring data is used and protected. This information is often available through the registrar's office or academic affairs department. Understanding these policies helps you know what data is collected, how long it is retained, and under what circumstances it might be reviewed.
