Your system administrator may provide you with a VIP credential that allows you to authenticate and get access to resources protected with Defender. Before you start using the VIP credential for authentication, you need to register it. You can have your system administrator register the VIP credential for you or you can self-register the VIP credential on a Web site known as the Defender Self-Service Portal.
Contact your system administrator to learn if you can use the Defender Self-Service Portal to register your VIP credential and to obtain the address (URL) of the portal Web site.
