 For Azure Kubernetes Service (AKS) clusters, the OIDC issuer and workload identity features can be enabled only at the time of cluster creation. For clusters on AKS Edge Essentials, the automated script enables these features by default. For AKS clusters on Azure Local, follow the steps to [Deploy and configure workload identity on an AKS enabled by Azure Arc cluster](/azure/aks/aksarc/workload-identity) to create a new cluster if you don't have one with the required features.

 ## Set up secrets management
 
-Secrets management for Azure IoT Operations uses the Secret Store extension to sync the secrets from an Azure key vault and store them on the edge as Kubernetes secrets. The Secret Store extension requires a user-assigned managed identity with access to the Azure key vault where secrets are stored.

     - Creates a federated identity credential by using the user-assigned managed identity.
