OpenEdX does not currently offer built-in password protection, to lock an assessment from students accessing it until a password is entered. This makes it difficult to restrict access to students from submitting the assessment from off-campus (home). This workaround method is proposed to add password protection to an assessment.
Grading - Assignment Type
For each assessment that you wish to lock with a password, create a separate Assignment Type.
From the CMS, go to Settings → Grading.
Click the +New Assignment Type button.
Enter the Assignment Type Name (e.g.
Password Protection 1).Enter the Abbreviation (e.g.
PW1).For the Weight of Total Grade enter
10. While it might be possible to enter a weighting of zero, that has not been tested yet.
