IGEL recommends automatic registration when registering new IGEL OS 11 devices for the first time during the rollout. You can use automatic registration also for IGEL OS 12 devices that are inside the company network; for IGEL OS 12 devices outside the company network, it is preferable to use IGEL Onboarding Service, see Initial Configuration of the IGEL Onboarding Service (OBS) and Onboarding IGEL OS 12 Devices.
Disable automatic registration as soon as all devices have been registered, so that no unknown devices can obtain sensitive settings.
