Abstract: A replaceable item for a host device, such as a print substance cartridge for a printing device, stores multiple identities. For each identity, the replaceable item stores multiple authentication values, or passwords. The replaceable item selects an identity, and in response to a request for an authentication value from the host device, sends the requested authentication value for the selected identity.

Abstract: Example implementations relate to secure messages for IoT devices. For example, a system for secure messages for IoT devices may include an IoT device coupled to a network including a plurality of web services. The IoT device may store a service certificate for each of the plurality of web services, generate a secure message for a web service among the plurality of web services using the stored service certificate for the web service, and send the secure message to the web service without first establishing a connection between the IoT device and the web service.
