If access another super-user account is available, then the password can be reset using the Django admin interface. For the mecheng server, the admin interface is located at https://mecheng.up.ac.za/admin
Alternatively, a new super-user account can be created using the manage.py script. For example after logging in the mecheng server simply
cd ~/website_ProjectAssignment/
./manage.py createsuperuser
then use that newly created super-user to set the password for the account which requires password recovery.
Lecturers and Students can reset their passwords using the reset password link which is on the login screen of project assignment website.
