+#### Authentication
+The Azure Storage linked service for ADLS Gen2 now supports system-assigned and user-assigned managed identities in addition to the existing authentication methods. This support is available by default when using Azure Integration Runtime (Azure IR) and is supported in Self-hosted Integration Runtime (SHIR) starting from version 5.55.9306.2 or later.
+For Azure Blob Storage, the Azure Storage linked service continues to support only account key authentication.
+Cluster managed identity authentication is also now available by default when using Azure IR and supported on SHIR beginning with version 5.58 or later. When creating a cluster, only one authentication method can be used per cluster. For details on creating and managing clusters with managed identity, see [Create and manage Azure HDInsight cluster with Entra ID authentication](../hdinsight/hdinsight-with-entra-authentication/create-clusters-with-entra.md)

 > [!IMPORTANT]
 > HDInsight supports multiple Hadoop cluster versions that can be deployed. Each version choice creates a specific version of the Hortonworks Data Platform (HDP) distribution and a set of components that are contained within that distribution. The list of supported HDInsight versions keeps being updated to provide latest Hadoop ecosystem components and fixes. Make sure you always refer to latest information of [Supported HDInsight version and OS Type](../hdinsight/hdinsight-component-versioning.md#supported-hdinsight-versions) to ensure you are using supported version of HDInsight.

-> In addition to the already supported authentication methods, the Azure Storage linked service for ADLS Gen2 now supports both system-assigned and user-assigned managed identities as authentication types. This support is available by default when using Azure Integration Runtime (Azure IR). For Self-hosted Integration Runtime (SHIR), it is supported starting from version 5.55.9306.2 and above. The Azure Storage linked service configured with Azure Blob Storage continues to support only account key authentication.
