Azure Automation Run As accounts retiring on 30 September 2023

On 30 September 2023, Azure Automation will retire Run As accounts, and completely move to Managed identities. All runbook executions using Run As accounts, including Classic Run As accounts would not be supported after this date. Moreover, starting 1 April 2023, creation of new Run As accounts in Azure Automation will not be possible. Renewing of certificates for existing RunAs accounts would be possible only till the end of support.

To ensure you are using a supported authentication method, you must migrate all your runbooks to Managed Identities.
