I am wondering how I can password protect an assignment the way I would a quiz? We have quiz items that are delivered to us and graded via an LTI external tool from a vendor. As a result, all of the items are considered assignments with an external tool submission type. Because these items are really exams (module, midterm, final exams) I would like a way to password protect them (we require that proctors enter the passwords for the students).
If it is not possible any workarounds that people have found useful?
