Samigo > Further qualify password field label for clarity

It's been reported that users have erroneously input their own institutional passwords into this field, thinking it required their personal password to save the settings. This resulted in students not being able to take said quizzes because they obviously did not know the instructors' password, and the instructor clearly would not distribute their personal passwords to students. This was further complicated in older Sakai installations where there was also a 'Username' field, which may have prompted some browsers to automatically fill in these fields with saved values.

To try to prevent the issue from occurring, and to make the assessment password field less confusing for some users, the linked PR proposes changing the label to be "Assessment Password", rather than just "Password".
