AWS – AWS IoT Core now supports Multi-Account Registration certificates on IoT Credential Provider endpoint
You can now use Multi-Account Registration certificates on AWS IoT Core Credential Provider endpoints. Multi-Account Registration is a feature of AWS IoT Core that makes it easy for customers to register and use the same device certificate across multiple AWS accounts and endpoints. For example, a customer could register the same certificate with testing and production accounts. Customers can subsequently move devices easily between these AWS accounts by specifying the account endpoint when devices connect to AWS IoT Core. Until now, Multi-Account Registration certificates were supported only on IoT data plane and IoT Jobs endpoints. Starting today, customers can also use Multi-Account Registration certificates on IoT Credential Provider endpoints. See AWS IoT device data and service endpoints for more details.
