MediaDeviceInfo.deviceId

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The deviceId readonly property of the MediaDeviceInfo interface returns a DOMString that is an identifier for the represented device and 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.
