Client certificates

The client certificates allow the authentication to be restricted so that only certain clients that have the certificate can access the server and thus the HMI. All other clients that do not have the certificate will not have access to the server. A so-called client certificate, which can be generated and signed by TwinCAT HMI in the engineering department, must be installed in the respective client. The server-side part of the certificate is automatically stored as the remote terminal in the TwinCAT HMI server during generation. A client certificate can optionally be assigned to a user so that the user is automatically logged in via the client certificate.

The use of client certificates is optional.
