# UpdateCertificate
<a name="API_UpdateCertificate"></a>

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

Requires permission to access the [UpdateCertificate](https://docs.aws.amazon.com/service-authorization/latest/reference/list_awsiot.html#awsiot-actions-as-permissions) action.

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

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