How to renew the certificate of a device
If you have activated IAM, you may need certain IAM permissions to carry out some actions described on this page. This means:
- you are the Owner of the Scaleway Organization in which the actions will be carried out, or
- you are an IAM user of the Organization, with a policy granting you the necessary permission sets
- You have an account and are logged into the Scaleway console
- You have created an IoT Hub
- You have added a device
The renewal feature becomes unavailable once you have provided your own Hub certificate authority or previously replaced the device certificate since, in this case, the certificate authority is no longer managed by Scaleway.
The validity period of certificates generated by Scaleway is 10 years.
-
