Create your own client certificates - Amazon IoT Core
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.

Create your own client certificates

Amazon IoT supports client certificates signed by other root certificate authorities (CA). You can register client certificates signed by another root CA; however, if you want the device or client to register its client certificate when it first connects to Amazon IoT, the root CA must be registered with Amazon IoT.


A CA certificate can be registered by only one account in a Region.

For more information about using X.509 certificates to support more than a few devices, see Device provisioning to review the different certificate management and provisioning options that Amazon IoT supports.
