HELP-PROMPT: Enter the (encrypted) service credentials.
DESCRIPTION: The value of this field is a string containing encrypted data. This value contains the access and verify codes that the DICOM Gateway is allowed to use as a "service account" when the credentials that were provided by
the end-user during login expire during the course of the session.
This field is automatically populated when an end-user successfully logs in on a DICOM Gateway.
When a site decides not to have such a service account, the value of this field will be an encrypted value for the string ";".
