How Does Duo Work With LockDown Browser?

LockDown Browser does not support Touch ID for authentication with Duo. For this reason, we recommend adding an additional method of authentication to your Duo account such as Duo Mobile or phone authentication. Learn more about adding a device to your Duo account.

If you are taking a test with LockDown Browser for the first time and find that you're unable to authenticate, we recommend doing the following;

  1. Close LockDown Browser
  2. Restart your computer
  3. Open Google Chrome
  4. Following the instructions at the link above to access your Duo account and add an alternative method of authentication
  5. Sign in on LockDown Browser using this additional method of verification


Can I use LockDown Browser on a wireless connection?

While taking an online exam using Canvas, it is recommended that you use an Internet connection with a speed of at least 512 Kbps or higher while taking your exam in LockDown Browser. If you use a wireless UBS modem, laptop connect card, or mobile hotspot connection during an exam, you are more likely to run into problems due to dropped/interrupted connections to the Canvas server. This is because the Canvas server is more bandwidth-intensive (especially during exams) than normal Internet surfing.

If you lose your Internet connection during the exam, it will lock up the browser and not allow you to save answers, move on to other questions, submit or exit the exam. If you have a router, plugging directly into it when taking exams will reduce the chances of connection interruptions.

What do I do if my computer freezes while taking an exam?

If you lose your Internet connection while taking an exam or if you have outdated and/or multiple Java installations, the LockDown Browser and your computer may stop responding or freeze. Shut your computer down and restart. Depending on your system, this could take several minutes and will cause you to lose time on the exam. In most cases, as long as the time has not expired, it should let you back into the exam. As soon as you have completed the exam, immediately contact your instructor to let them know what happened.

What do I do if I'm having trouble connecting to the internet with LockDown Browser?

You may receive a message that you are unable to connect to the Internet when LockDown Browser is opened. If this occurs, choose "Yes" to run diagnostics and then run the Network Connection test. Look at the list of programs for any security, Internet or network programs. There may be multiple programs that could be stopping LockDown Browser from connecting to the Internet. Each program may need to be told to "trust" or "allow access" to the LockDown.exe program. If you are unsure how to do this, please contact the OIT Help Desk.

As a second check, verify the computer system clock is set to the correct date and time for your local time zone and verify the computer is synchronizing with an Internet time server in Windows: Control Panel > Date and Time or Mac: System Preferences > Date & Time.
