The device is authenticated through both device credentials and gateway
association. The device must be bound to the gateway and must provide its
own credentials.
AssociationOnly
The device is authenticated through the gateway association only. Device
credentials are ignored even if provided.
DeviceAuthTokenOnly
The device is authenticated through its own credentials. Gateway
association is not checked.
Unspecified
No authentication/authorization method specified. No devices are allowed to
access the gateway.
