# localParticipantIdentifier

A UUID that identifies the user on this device.

## Declaration

```swift
var localParticipantIdentifier: UUID { get }
```

## Discussion

Discussion This UUID is scoped to this device. It remains stable as long as the extension is enabled. If the extension is disabled and reenabled, or if the containing app is removed and reinstalled, the UUID for the local participant changes.
