 In IoT Hub, managed identities can be used for egress connectivity from IoT Hub to other Azure services for features such as [message routing](iot-hub-devguide-messages-d2c.md), [file upload](iot-hub-devguide-file-upload.md), and [bulk device import/export](iot-hub-bulk-identity-mgmt.md). In this article, you learn how to use system-assigned and user-assigned managed identities in your IoT hub for different functionalities.
