    ONAP Portal allowed to retrieve password of currently active user via
    "/portalApi/loggedinUser" endpoint. Prefilled "Login Password" field
     has been changed to "*****" and password is not send anymore to the
     frontend. Only after change of this default value
     password will be updated. Confirm Password field has been removed

     checked on the backend side to verify current password
     before updating it.
