Abstract
Apparatus, systems, methods, and related computer program products for synchronizing distributed states amongst a plurality of entities and authenticating devices to access information and/or services provided by a remote server. Synchronization techniques include client devices and remote servers storing buckets of information. The client device sends a subscription request to the remote serve identifying a bucket of information and, when that bucket changes, the remote server sends the change to the client device. Authentication techniques include client devices including unique default credentials that, when presented to a remote server, provide limited access to the server. The client device may obtain assigned credentials that, when presented to the remote server, provide less limited access to the server.
