Joe, what Dan is proposing is a reasonable way to use a one-time password for the initial provisioning of a trust anchor. Initial provisioning is important for many types of deployments. Does the document allow an alternative secure way to do that?

Dan, I suspect that for this specific use case (one time use, no need for confidentiality), resistance against dictionary attack is not very important. So EAP-GPSK inside the tunnel will do just as well.

Thanks,
	Yaron
