I use opc ua server on raspberry pi and I have one question: is there possibility to implement user authorization or any other way to limit user's acess to some data/features?
I'm investigating the same. Currently, the OPC server running in CODESYS V3 appears to allow any client to connect without authentication. They can then view the full tree, and read/write variables. This is very problematic. There are no options in the IDE that I can find for configuring the server, it is simply enabled in the Symbol Configuration. It appears the controller has an X.509 certificate but it doesn't require anything from the client. Does anyone have more information? The online videos from 3S worked to get me this far but they connected without authentication.
you are right, but the good news is:
This will be released with 3.5SP13 26th June.
I'm Currently setting up an OPC UA on 3.5 SP13, however I'm looking to see where you implement user and password authentication.
Is there anyone out there who can help?
I would start here:

So, is it possible to add user authentication in OPC UA? (raspberry pi + Codesys)
How do we do it?
