 > [!NOTE]
 > The IoT Hub identity registry only stores device and module identities to enable secure access to the IoT hub. The identity registry stores device IDs and keys to use as security credentials. The identity registry also stores an enabled/disabled flag for each device that you can use to disable access for that device. If your application needs to store other device-specific metadata, it should use an application-specific store. There is no enabled/disabled flag for module identities.
