Authentication methode unattended robot with orchestrator

For our client we need to figure out what kind of authentication methode is used when connecting an unattended robot with orchestrator via Client Secret and Machine Key. How secure is this methode in comparison to for example SSH key authentication. Also where is the Client Secret stored. Are there any other methods we can use to connect except from Client secret and Machine key? Thanks!
