This extension point enables you to provide the credentials to connect to z/OS.
An implementation of this extension point can cause the standard "Enter Password" dialog to be bypassed by providing the login credentials for the connection. A use case is that the login credentials are for example provided by an external login card reader so that there is no need for a password dialog. Another use case could be that there is a central login outside Eclipse for all user applications which has to be used in Eclipse when connecting to a remote system without an additional password request.
