 ## Configure username and password authentication
 
-First, configure the secrets for the username and password in Azure Key Vault and project them into the connected cluster by using a `SecretProviderClass` object.
-
-1. Configure the username and password in Azure Key Vault. In the following example, use the `username` and `password` as secret references for the asset endpoint configuration in the operations experience web UI.
-
-    Replace the placeholders for username and password with the credentials used to connect to the OPC UA server.
-
-    To configure the username and password, run the following code:
-
-    # [Bash](#tab/bash)
-
-    ```bash
-    # Create username Secret in Azure Key Vault
-    az keyvault secret set \
-      --name username \
-      --vault-name <your-azure-key-vault-name> \
-      --value <your-opc-ua-server-username> \
-      --content-type text/plain
-
-    # Create password Secret in Azure Key Vault
-    az keyvault secret set \
-      --name password \
-      --vault-name <your-azure-key-vault-name> \
-      --value <your-opc-ua-server-password> \
-      --content-type text/plain
-    ```
-
-    # [PowerShell](#tab/powershell)
-
-    ```powershell
-    # Create username Secret in Azure Key Vault
-    az keyvault secret set `
-      --name username `
-      --vault-name <your-azure-key-vault-name> `
-      --value <your-opc-ua-server-username> `
-      --content-type text/plain
-
-    # Create password Secret in Azure Key Vault
-    az keyvault secret set `
-      --name password `
-      --vault-name <your-azure-key-vault-name> `
-      --value <your-opc-ua-server-password> `
-      --content-type text/plain
-    ```

-1. Configure the `aio-opc-ua-broker-user-authentication` custom resource in the cluster. Use a Kubernetes client such as `kubectl` to configure the `username` and `password` secrets in the `SecretProviderClass` object array in the cluster.
-
-    The following example shows a complete `SecretProviderClass` custom resource after you add the secrets:
-
-    ```yaml
-    apiVersion: secrets-store.csi.x-k8s.io/v1
-    kind: SecretProviderClass
-    metadata:
-      name: aio-opc-ua-broker-user-authentication
-      namespace: azure-iot-operations
-    spec:
-      provider: azure
-      parameters:
-        usePodIdentity: 'false'
-        keyvaultName: <azure-key-vault-name>
-        tenantId: <azure-tenant-id>
-        objects: |
-          array:
-            - |
-              objectName: username
-              objectType: secret
-              objectVersion: ""
-            - |
-              objectName: password
-              objectType: secret
-              objectVersion: ""
-    ```
-
-    > [!NOTE]
-    > The time it takes to project Azure Key Vault certificates into the cluster depends on the configured polling interval.
