Please be aware that this plugin uses your university’s CampusNet service by contacting it directly. It also uses your university’s authentication system. Usernames and passwords are stored as WordPress users, so, they are just as secure as a normal WordPress user would be.
Use your university’s CampusNet login via their API. It requires a user to be a member of a specific CampusNet group (definable) to get access, that way, the administration of users is kept in one place (or, use group/elementid 0 to not use a group). For each user logging in, it makes sure that a WordPress user is created/exists, so if the CampuseNet API ever breaks, you can disable it and the users can login using the username and password they used earlier.
NOTE: it adds a checkbox on the login page that sets if the user is a student or not.
The best place to file a bug report or a feature request is using Github issues, which is checked far more often than the support section here (which I, of course, still do check).
