It relies on WinCC’s user groups or Windows authentication. Stateless token-based auth (like JWT) is absent for older versions. In practice, you either use session cookies (stateful) or Basic auth over HTTPS — which feels out of place in a modern cloud-native world. If you'd like to start developing with the
Siemens' WinCC (Windows Control Center) is a popular Human-Machine Interface (HMI) software used for monitoring and controlling industrial processes.
