Does Mixpanel track which devices a user is logged in on

Mixpanel does not explicitly track or display a list of devices a user is logged in on. However, Mixpanel’s identity management system (using either the Simplified or Original ID Merge API) merges anonymous device identifiers ($device_id) with a user’s authenticated identifier ($user_id) when the user logs in. This means that Mixpanel can associate events from multiple devices to a single user profile by merging their device IDs into one identity cluster when the user logs in on each device.For example, if a user logs in on both a web browser and a mobile app, Mixpanel will merge the $device_id from each device with the user’s $user_id, so all activity is attributed to the same user. While this allows Mixpanel to attribute events from multiple devices to a single user, it does not provide a direct report or property listing all devices a user is currently logged in on. The device information is available in event properties (such as $device_id, $os, $browser, etc.), and you can analyze events by these properties, but there is no built-in feature to see a list of active devices per user profile Identifying Users (Simplified) Identity Management in Action.In summary: Mixpanel can associate events from multiple devices to a user, but it does not automatically track or display a list of devices a user is logged in on.
