OPC UA Client Authentication Settings
OPC UA provides three authentication methods to logon to a server:
 Anonymous,
 Username/Password, and
 Certificate-based.
The OPC UA server supports Anonymous and Username/Password Authentication methods. Machine Edition
controller project settings determine the Authentication method used by the OPC UA server.
Anonymous Authentication
You enable OPC UA server Anonymous Authentication by disabling Controller passwords. Machine Edition is
used to disabled controller passwords. To access this setting using Machine Edition, open the Controller
hardware configuration with the Project tab within the Navigator, expand the hardware configuration, and
select the controller. Double-click the controller tree node to access the controller-specific hardware
configuration settings. Select the Settings tab, then set the Passwords parameter to Disabled (see screenshot
below).
