Work with account keys and connection strings for an Azure Cosmos DB account using Azure CLI

APPLIES TO: NoSQL MongoDB Cassandra Gremlin Table

The script in this article demonstrates four operations.

  • List all account keys
  • List read only account keys
  • List connection strings
  • Regenerate account keys

This script uses a API for NoSQL account, but these operations are identical across all database APIs in Azure Cosmos DB.

If you don't have an Azure subscription, create an Azure free account before you begin.


  • This article requires version 2.9.1 or later of the Azure CLI. If using Azure Cloud Shell, the latest version is already installed.

Sample script

Launch Azure Cloud Shell

The Azure Cloud Shell is a free interactive shell that you can use to run the steps in this article. It has common Azure tools preinstalled and configured to use with your account.

To open the Cloud Shell, just select Try it from the upper right corner of a code block. You can also launch Cloud Shell in a separate browser tab by going to

When Cloud Shell opens, verify that Bash is selected for your environment. Subsequent sessions will use Azure CLI in a Bash environment, Select Copy to copy the blocks of code, paste it into the Cloud Shell, and press Enter to run it.

Sign in to Azure

Cloud Shell is automatically authenticated under the initial account signed-in with. Use the following script to sign in using a different subscription, replacing <Subscription ID> with your Azure Subscription ID. If you don't have an Azure subscription, create an Azure free account before you begin.

subscription="<subscriptionId>" # add subscription here

az account set -s $subscription # ...or use 'az login'

For more information, see set active subscription or log in interactively

Run the script

# Account key operations for an Azure Cosmos account

Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="East US"
account="msdocs-account-cosmos-$randomIdentifier" #needs to be lower case

# Create a resource group
echo "Creating $resourceGroup in $location..."
az group create --name $resourceGroup --location "$location" --tags $tag

# Create a Cosmos DB account with default values
# Use appropriate values for --kind or --capabilities for other APIs
echo "Creating $account for CosmosDB"
az cosmosdb create --name $account --resource-group $resourceGroup

# List all account keys
az cosmosdb keys list --name $account --resource-group $resourceGroup

# List read-only keys
az cosmosdb keys list --name $account --resource-group $resourceGroup --type read-only-keys

# List connection strings
az cosmosdb keys list --name $account --resource-group $resourceGroup --type connection-strings

# Regenerate secondary account keys
# key-kind values: primary, primaryReadonly, secondary, secondaryReadonly
az cosmosdb keys regenerate --name $account --resource-group $resourceGroup --key-kind secondary

Clean up resources

Use the following command to remove the resource group and all resources associated with it using the az group delete command - unless you have an ongoing need for these resources. Some of these resources may take a while to create, as well as to delete.

az group delete --name $resourceGroup

Sample reference

This script uses the following commands. Each command in the table links to command specific documentation.

Command Notes
az group create Creates a resource group in which all resources are stored.
az cosmosdb create Creates an Azure Cosmos DB account.
az cosmosdb keys list List the keys for an Azure Cosmos DB account.
az cosmosdb list-read-only-keys List the read only keys for an Azure Cosmos DB account.
az cosmosdb list-connection-strings List the connection strings for an Azure Cosmos DB account.
az cosmosdb regenerate-key Regenerate keys for an Azure Cosmos DB account.
az group delete Deletes a resource group including all nested resources.
