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.deviceIdValue
A DOMString.
