User account credentials, and then responses to a third party RADIUS server. System authentication + RADIUS authentication User account credentials, provided transparently.Īn X.509 certificate, provided transparently. User account email, and then responses to one or more PAM modules. However, it may be useful in the context of some regulatory compliance regimes, to guarantee that session data will never be transmitted via third party servers.Īn equivalent VNC Viewer AllowCloudRelay parameter is available to prevent cloud connections from particular desktop computers. Setting this parameter to FALSE will cause an unquantifiable percentage of cloud connections to fail. Note that session data relayed via our cloud service is encrypted end-to-end, so cannot be deciphered by RealVNC, nor anyone else. However, intermediate network hardware may mean this is not possible, so the cloud service automatically falls back to relaying session data this ensures cloud connections succeed. Where possible, the cloud service then negotiates peer-to-peer sessions between endpoints, so session data is transmitted directly between them this is likely to be more performant. Specify FALSE to prevent cloud connections to the VNC Server computer if they would be relayed via RealVNC’s cloud service.Īll cloud connections are brokered by RealVNC’s cloud service.
