Safe Access Key Rotation Sequence

To rotate keys safely, follow this specific sequence: first, update all connection strings in your applications to reference the secondary access key instead of the primary. Second, regenerate the primary key and wait until your application successfully uses the new key. Third, update connection strings again to reference the new primary key. Finally, regenerate the secondary key so that both keys have been rotated. This approach ensures your applications maintain continuous access to storage throughout the rotation process.

You can enforce rotation reminders by creating a key expiration policy and monitoring compliance with Azure Policy. After setting up the policy, you will receive a reminder when the specified interval elapses. Use Azure Policy's built-in definition Storage account keys should not be expired to audit your accounts and identify any storage accounts with keys that have exceeded your rotation schedule. This integration ensures continuous compliance with your organization's key rotation requirements.
