This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The deviceId readonly property of the MediaDeviceInfo interface returns a DOMString that is an identifier for the represented device that is persisted across sessions. It is un-guessable by other applications and unique to the origin of the calling application. It is reset when the user clears cookies (for private browsing, a different identifier is used that is not persisted across sessions).

Syntax

var deviceID = MediaDeviceInfo.deviceId

Value

A DOMString.
