Embodiments facilitate the management of security certificates for third-party services being used to print documents from kiosks in public locales. The system establishes a gateway connection between a cloud-based host server, the third-party service, and the kiosk. When a user wishes to use the third-party service to print a document requested through the kiosk, the host server obtains the security certificate and installs the certificate in the kiosk. The kiosk may then request the document from the third-party service which forwards the document upon authentication of the security certificate details registered in the kiosk.
