+
+## Introduction
+
+An Azure storage account serves as a centralized container for all your data objects, including blobs, files, queues, and tables. It provides a unique, globally accessible namespace reachable via HTTP or HTTPS. For more information, see [Overview of storage accounts](https://learn.microsoft.com/en-us/azure/storage/common/storage-account-overview).
+
+LocalStack for Azure provides a local environment for building and testing applications that make use of blobs, queues, and tables. For more information, see:
+
+- [Blob Storage](/azure/services/blob-storage)
+- [Queue Storage](/azure/services/queue-storage)
+- [Table Storage](/azure/services/table-storage)
+
+The supported APIs are listed in the [API Coverage](#api-coverage) section.
+
+## Getting started
+
+This guide is designed for users new to Azure Storage Accounts and Blob Storage and assumes basic knowledge of the Azure CLI and our `azlocal` wrapper script.
+
+Start your LocalStack container using your preferred method. For more information, see [Introduction to LocalStack for Azure](/azure/getting-started/).
+
+:::note
+As an alternative to using the `azlocal` CLI, customers can run `az start-interception`. This command points the `az` CLI away from the public Azure cloud management API and toward the local emulator API.
+To revert this configuration, use `azlocal stop-interception`, which re-configures the CLI to send commands to the official Azure platform management REST API.
+At this time, there is no full parity between `azlocal` commands and `az` commands after running `az start-interception`. Therefore, this technique is not fully interchangeable.

+
+### Create a resource group
+
+Create a resource group for your storage account resources:
+
+```bash
+azlocal group create \
+  --name rg-storage-demo \
+  --location westeurope
+```
+
+```bash title="Output"
+{
+  "id": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/rg-storage-demo",
+  "location": "westeurope",
+  "managedBy": null,
+  "name": "rg-storage-demo",
+  "properties": {
+    "provisioningState": "Succeeded"
+  },
+  "tags": null,
+  "type": "Microsoft.Resources/resourceGroups"
+}
+```
+
+### Create a storage account
+
+Create a storage account with the `StorageV2` kind and `Standard_LRS` SKU:
+
+```bash
+azlocal storage account create \
+  --name stordoc86acct \
+  --resource-group rg-storage-demo \
+  --location westeurope \
+  --sku Standard_LRS \
+  --kind StorageV2
+```
+
+```bash title="Output"
+{
+  ...
+  "id": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/rg-storage-demo/providers/Microsoft.Storage/storageAccounts/stordoc86acct",
+  ...
+  "kind": "StorageV2",
+  "location": "westeurope",
+  "name": "stordoc86acct",
+  ...
+  "primaryEndpoints": {
+    "blob": "https://stordoc86acctblob.localhost.localstack.cloud:4566",
+    "queue": "https://stordoc86acctqueue.localhost.localstack.cloud:4566",
+    "table": "https://stordoc86accttable.localhost.localstack.cloud:4566",
+    ...
+  },
+  "provisioningState": "Succeeded",
+  ...
+}
+```
+
+### Authentication
+
+There are three ways to authenticate storage blob commands against the emulator:
+
+#### Storage account key
+
+Retrieve the account key and pass it with `--account-name` and `--account-key`:
+
+```bash
+ACCOUNT_KEY=$(azlocal storage account keys list \
+  --account-name stordoc86acct \
+  --resource-group rg-storage-demo \
+  --query "[0].value" \
+  --output tsv)
+
+azlocal storage container list \
+  --account-name stordoc86acct \
+  --account-key "$ACCOUNT_KEY"
+```
+
+#### Login credentials
+
+Use `--auth-mode login` to authenticate with the current session credentials:
+
+```bash
+azlocal storage container list \
+  --account-name stordoc86acct \
+  --auth-mode login
+```
+
+#### Connection string
+
+Bundle the account name and key into a single value:
+
+```bash
+CONNECTION_STRING=$(azlocal storage account show-connection-string \
+  --name stordoc86acct \
+  --resource-group rg-storage-demo \
+  --query connectionString -o tsv)
+
+azlocal storage container list \
+  --connection-string "$CONNECTION_STRING"
+```
+
+The remaining examples in this guide use connection strings for brevity.
+
+### Manage account keys and connection string
+
+List the storage account access keys:
+
+```bash
+azlocal storage account keys list \
+  --account-name stordoc86acct \
+  --resource-group rg-storage-demo
+```
+
+```bash title="Output"
+[
+  {
+    "keyName": "key1",
+    "permissions": "FULL",
+    "value": "MWFjYTgyZjgtYzU0My00NjE0LThmZDctNzlkODg5ZjU4ZTE5",
+    "..."
+  },
+  {
+    "keyName": "key2",
+    "permissions": "FULL",
+    "value": "NzliNzVhN2EtYTcwZC00ZTg4LWJkMTQtYjg4MWNlMDJjZDcx",
+    "..."
+  }
+]
+```
+
+Regenerate the primary key:
+
+```bash
+azlocal storage account keys renew \
+  --account-name stordoc86acct \
+  --resource-group rg-storage-demo \
+  --key key1
+```
+
+Fetch a connection string for data-plane operations:
+
+```bash
+azlocal storage account show-connection-string \
+  --name stordoc86acct \
+  --resource-group rg-storage-demo
+```
+
+```bash title="Output"
+{
+  "connectionString": "DefaultEndpointsProtocol=https;EndpointSuffix=localhost.localstack.cloud:4566;AccountName=stordoc86acct;AccountKey=...;BlobEndpoint=https://stordoc86acctblob.localhost.localstack.cloud:4566;FileEndpoint=https://stordoc86acctfile.localhost.localstack.cloud:4566;QueueEndpoint=https://stordoc86acctqueue.localhost.localstack.cloud:4566;TableEndpoint=https://stordoc86accttable.localhost.localstack.cloud:4566"
+}
+```
+
+## Features
+- **Control plane REST API**: Storage account CRUD (create, read, update, delete, list), account key management, and name availability checks via Azure Resource Manager.
+- **Multiple authentication modes**: Storage account key, login credentials, and connection strings.
+- **Storage account management**: Create, update, delete, and list storage accounts. Supports `StorageV2`, `BlobStorage`, and `Storage` account kinds with configurable SKU, access tier, and TLS version.
+- **Account key management**: List and regenerate storage account keys (`key1`/`key2`).
+- **Connection string generation**: Retrieve ready-to-use connection strings containing all service endpoints (Blob, Queue, Table, File).
+
+## Limitations
+- **Header validation**: Unsupported request headers or parameters are silently accepted instead of being rejected.
+- **API version enforcement**: The emulator does not validate the `x-ms-version` header; all API versions are accepted.
