Kingo Portal (campus SSO and gated student systems)
Kingo Portal is SKKU's single sign-on environment, the front door to the university's own online services — Google Workspace, GLS, iCampus (icampus.skku.edu, a Laravel learning system on SKKU's domain), course registration (sugang.skku.edu), electronic approval and notice boards — plus eduroam federated Wi-Fi roaming, which uses the same institutional identity that the KAFE/eduGAIN identity provider publishes. Every one of these systems is institution-operated and every one is enrolment-gated: there is no publicly documented authentication API, no developer registration, no published rate limits and no machine-readable course catalog. Probed rather than assumed — icampus.skku.edu/api/v1/courses returns 419 (Laravel CSRF) and every other API path returns the application's Korean 404 page.
