""LockDown Browser

The Respondus LockDown Browser (RLDB) is a locked browser that prevents students from printing, copying, going to another URL, or accessing other applications during an assessment. When the RLDB is enabled for a quiz, students will be required to download and use RLDB to take the quiz or exam. Watch an overview video on LockDown Browser.


Respondus Monitor is an automated proctoring feature that can be turned on when using the LockDown Browser that uses a student’s webcam and video analytics to help instructors catch cheating. Watch an overview video on Monitor.

See comparison of proctoring services available at UAB.

Who can enable LockDown Browser and access the Dashboard Results?

Only users with a “teacher” role in Canvas courses are able to access the Respondus LockDown Browser Link in the course navigation. Users with “Instructional Designer” or “Teaching Assistant” role can still create quizzes but only users with “teacher” role can enable the RLDB or access the dashboard to see results.

What should I say in my Syllabus?

The sample text below can be used in your course or syllabus. It explains that students must use LockDown Browser for their online tests and possibly use a webcam.

Using LockDown Browser and a Webcam for Online Exams

This course requires the use of LockDown Browser and a webcam for online exams. The webcam can be built into your computer or can be the type that plugs in with a USB cable. Watch this short video to get a basic understanding of LockDown Browser and the webcam feature. A student pdfQuick Start Guide is also available.

Then download and install LockDown Browser.


To ensure LockDown Browser and the webcam are set up properly, do the following:

  • Start LockDown Browser, log into uab.instructure.com, and select this course.
  • Locate and select the Help Center button on the LockDown Browser toolbar.
  • Run the Webcam Check and, if necessary, resolve any issues.
  • Run the System & Network Check. If a problem is indicated, see if a solution is provided in the Knowledge Base.
  • Upon completing and submitting the practice quiz, exit LockDown Browser.
Taking the Exam

When taking an online exam that requires LockDown Browser and a web cam, remember the following guidelines:

  • Ensure you're in a location where you won't be interrupted.
  • Turn off all other devices (e.g. tablets, phones, second computers) and place them outside of your reach.
  • Clear your desk of all external materials not permitted — books, papers, other devices.
  • Before starting the test, know how much time is available for it, and that you've allotted sufficient time to complete it.
  • Remain at your computer for the duration of the test.
  • If the computer or networking environment is different than what was used previously with the Webcam Check and System & Network Check in LockDown Browser, run the checks again prior to starting the test.
  • To produce a good webcam video, do the following:
    • Avoid wearing baseball caps or hats with brims.
    • Ensure your computer or tablet is on a firm surface (a desk or table). Do NOT have the computer on your lap, a bed, or other surface where the device (or you) are likely to move.
    • If using a built-in webcam, avoid tilting the screen after the webcam setup is complete.
    • Take the exam in a well-lit room and avoid backlighting, such as sitting with your back to a window.
  • Remember that LockDown Browser will prevent you from accessing other websites or applications; you will be unable to exit the test until all questions are completed and submitted.

Does any other software need to be installed to use the webcam with LockDown Browser?


The webcam features used by Respondus Monitor are built into LockDown Browser, so no other Respondus software needs to be installed.

We bundle Adobe's Flash Installer with LockDown Browser (Windows) because Flash is needed for Respondus Monitor. The version of Flash we include is not always the latest available, as Flash updates are frequent. If necessary, Windows users can download the most current version of the PPAPI Flash plugin:

  • select your operating system
  • choose ""FPnn for Opera and Chromium - PPAPI" {where nn=the current version number of the Flash plugin.)

Mac users should use only the Safari browser to download the most current version of the Flash PPAPI plugin.

How long does it take for videos to appear in the LockDown Browser Dashboard?

The average time for an exam video to be processed and available to an instructor is eight hours. The time can be greater during periods of high volume, and may take up to 24 hours. During periods of low volume, the time to process the video is roughly equal to the actual length of the video.

How much bandwidth is required for Respondus Monitor to run?

There isn’t a specific kb/s requirement for using a webcam with Respondus Monitor because the recording quality automatically adjusts when a slower connection is detected.

Generally speaking, if the user has a decent broadband connection that doesn’t result in significant delays when accessing the learning system, the bandwidth will be fine for Respondus Monitor. If using a shared Internet connection, students should ensure that others on the same connection don’t use bandwidth-hungry services during the exam (such as online movies, games, file sharing, etc.).

Below are some tips to help ensure the best results:

  • If possible, plug an Ethernet cable into the computer to ensure the best possible network connection/speed. Otherwise, be as close to the Wi-Fi router as possible.
  • Shut down all other applications other than LockDown Browser. This will help reduce the bandwidth being used by other applications running in the background.

Is LockDown Browser accessible to those with disabilities?

The Mac version of LockDown Browser works with VoiceOver (the standard screen reader that comes with the Mac OS). LockDown Browser's functions and security remain the same when VoiceOver is used. Be sure you are using LockDown Browser version or newer.

As of LockDown Browser for Windows, accessibility is enabled for all users. Improvements to accessibility were added to version for Windows. Please have all students on Windows platforms upgrade to version and newer. The Windows version of LockDown Browser allows a student to use some screen reader accessibility programs, such as NVDA, JAWS, MS-Windows Narrator, ReadSpeaker webReader, and Windows-Eyes. In our experience, NVDA works the best. NVDA is free and available to download.

  • Zoom Text is compatible in regards to increasing the text size, but the reader is not currently compatible.
  • Read&Write Gold, Kurzweil 3000 are not compatible with LockDown Browser. Most "literacy" programs like these have a number incompatibilities and potential exploits that cannot be addressed in LockDown Browser. These programs are standalone Windows programs which cannot be brought on top of an active LockDown Browser exam. Also, for use with a browser, these programs require a custom browser plug-in that is not compatible with LockDown Browser.
  • For "speech to text" with Dragon Naturally Speaking, users have reported adjusting the settings to "not use the dictation box" in Dragon Naturally Speaking, will allow it to work with LockDown Browser.

To upgrade LockDown Browser, either download and install the full installation package, or start LockDown Browser, select the “i” button from the toolbar (Windows) or "about" button (Mac) and then click “Check for Newer Version”. The version will be displayed and you will be able to download a newer version if one is available.

Keep in mind that the security level of LockDown Browser is lowered when screen readers are used.

Can Spreadsheets be used with LockDown Browser?

LockDown Browser includes a tool that enables .xls/.xlsx spreadsheets (csv not supported) to be viewed and manipulated during an exam session. This functionality is available for Windows, Mac, and iPad editions of LockDown Browser.

Within the quiz tool of the learning system, an instructor should embed/insert the spreadsheet file in the question wording. When a student selects the link within LockDown Browser, an Excel-like spreadsheet tool will open. The spreadsheet can be pre-populated with content or it can be a blank spreadsheet created in Excel that students use to prepare their answers.

As an example, the spreadsheet tool might be used with a multiple choice question. As shown below, a link provides access to a pre-populated spreadsheet. The student calculates the answer and then selects one of the answer choices.

Screenshot of an RLDB multiple choice question.

The image below shows the spreadsheet that was used for this exam question.

Screenshot of an RLDB spreadsheet.

Alternatively, an instructor can require students to create or modify a spreadsheet and submit it for grading. The example below shows how a short answer or essay question can be used for this purpose.

Screenshot of an RLDB essay question.

The question wording itself should provide guidance on the steps a student should follow. As shown above, students are instructed to:

  1. select the link that opens a pre-populated spreadsheet,
  2. create the required formula or calculation,
  3. select the button “Click here to save your work”, and
  4. paste the resulting URL into the answer field for the essay or short answer question.

After the spreadsheet file has been saved, a dialog will remind students to copy the resulting URL to the answer field using CTRL + V.

Screenshot of the reminder to students copy the link.

Following the exam, the instructor will see a unique URL within the LMS for each student who provided an answer for the essay or short answer question. Upon selecting the URL with a standard browser (not LockDown Browser), the Excel-like spreadsheet tool will open and the student’s work will be shown for that question.

What do I do if I have downloaded LockDown Browser, but it is still asking me to download?

LockDown Browser (LDB) is a completely separate browser not a plug in. After downloading the LDB, the student needs to open the LockDown Browser software (found in applications) and access the exam through that browser. If the student is getting a message saying to download LDB, then they are still accessing the exam through a normal browser like Chrome, Firefox, Edge or Safari.

Respondus offers webinars on this topic periodically.

Group, one-on-one, or virtual sessions are also available to faculty.
