The Respondus LockDown Browser application is a separate browser that your instructor may require to take a test in Blackboard. If a test in Blackboard says Requires Respondus LockDown Browser, you cannot take the test using a standard browser such as Safari, Firefox, Chrome, or Edge. The LockDown Browser application only needs to be installed one time on a computer. Instructors choose if a Blackboard test requiring LockDown Browser also requires a webcam.
