Create your own client certificates - AWS IoT

Create your own client certificates

AWS 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 AWS IoT, the root CA must be registered with AWS IoT.

Note

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 AWS IoT supports.
