MediaDeviceInfo: deviceId property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2017.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The deviceId read-only property of the MediaDeviceInfo interface returns a string 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.

Value

A string.
