updateCertificate

Updates the status of the specified certificate. This operation is idempotent.

Requires permission to access the UpdateCertificate action.

Certificates must be in the ACTIVE state to authenticate devices that use a certificate to connect to IoT.

Within a few minutes of updating a certificate from the ACTIVE state to any other state, IoT disconnects all devices that used that certificate to connect. Devices cannot use a certificate that is not in the ACTIVE state to reconnect.
