Not within Ignition, no. Java doesn’t expose anything like that because it varies so much among the supported platforms. I understand there are a number of third-party applications in Windows that can help with this (there definitely used to be – I hardly do any windows now-a-days). It’s relatively simple in Linux to launch an Ignition client in place of the desktop in select user accounts, logging off if the client exits.
