Currently, if COM API try to log in and it's used on other computer, the login dialog appears and requires confirmation. Is there a way to by pass the login screen and automatically log in to Eikon? Programatically or using some flag/settings of the Eikon itself.
No, there's no way to do this. The warning that requires user action is deliberate. It prevents someone who obtained your Eikon account credentials from completely highjacking your Eikon account by automatically signing in as soon as soon as logoff due to exclusive sign on is detected.
