Managing Access Keys in Microsoft Azure is an integral part of the AZ-104 Microsoft Azure Administrator exam. This involves understanding how to create, view, regenerate, and manage access keys, which enable one to interact with Azure resources.
Generating and Viewing Access Keys
First and foremost is the ability to generate and view access keys. Azure uses two types of keys: Primary and Secondary keys. They are interchangeable but provide a seamless transition while regenerating keys.
Access Keys for a storage account in Azure can be generated and viewed from the Azure portal.
Here are the steps:
- Go to the Azure portal.
- Select All services and in the list of resources, type Storage Accounts.
- Once you’re on the ‘Storage Accounts’ window, select the name of the storage account for which you want to create the access keys.
- In the Settings section, select Access keys.
Here you will see your Account name, two Key values (key1 and key2), and two Connection string values.
Regenerating Access Keys
The next crucial part of managing access keys is regenerating them. Regenerating the access keys is an essential security best practice because it prevents unauthorized access. It’s highly recommended to regenerate access keys regularly and whenever a security breach is suspected.
- Follow the steps outlined above to reach the ‘Access keys’ section.
- Select the key that you wish to regenerate (either key1 or key2) and then click the ‘Regenerate’ button.
Remember that regenerating a key invalidates the previous key and can lead to a temporary disruption of the service if the storage account is being actively used.
Managing Access Keys
The final aspect is managing access keys, this involves being able to update, delete, and monitor usage of access keys effectively. Azure provides features that can help you with management.
Azure Key Vault is a resource for storing and managing cryptographic keys and other sensitive data. Managing your access keys with Azure Key Vault enables you to avoid storing keys in your code, ensure your keys can be easily rotated, centrally manage key access policies, and monitor key usage.
Example of how to manage access keys with Azure Key Vault:
- Create a Key Vault.
- Create an Access Policy that gives user permissions to List, Set, Get, and Delete keys.
- Store your access keys within the Key Vault.
Using Azure Key Vault improves the security of your data by ensuring that all keys are stored securely and cannot be viewed or modified by unauthorized individuals.
If you suspect that a key is compromised, you can quickly disable or delete it from the Key Vault. This action prevents further access to your resources.
Remember to keep monitoring your keys for usage and automatically rotate them using the Azure functions whenever necessary.
In conclusion, understanding how to manage access keys in Azure is a critical part of the AZ-104 Microsoft Azure Administrator exam. With this knowledge, one can ensure secure and seamless connections to Azure resources while preventing unauthorized access.

Interview Questions
Question 1: How can you regenerate a storage account access key in Azure?
Answer: To regenerate a storage account access key in Azure, you can use the Azure portal, Azure PowerShell, Azure CLI, or Azure Storage Service REST.
Question 2: What is the purpose of access keys in Azure?
Answer: Access keys in Azure are used to authenticate applications and services when they communicate with Azure storage accounts, Cosmos DB, event hubs, etc.
