Reference documentation and code samples for the Cloud IoT V1 API module Google::Cloud::Iot::V1::GatewayAuthMethod.
The gateway authorization/authentication method. This setting determines how
Cloud IoT Core authorizes/authenticate devices to access the gateway.
Constants
GATEWAY_AUTH_METHOD_UNSPECIFIED
value: 0 No authentication/authorization method specified. No devices are allowed to
access the gateway.
ASSOCIATION_ONLY
value: 1 The device is authenticated through the gateway association only. Device
credentials are ignored even if provided.
DEVICE_AUTH_TOKEN_ONLY
value: 2 The device is authenticated through its own credentials. Gateway
association is not checked.
ASSOCIATION_AND_DEVICE_AUTH_TOKEN
value: 3 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.
