# externalContentProtectionStatus

The external protection status for the content key based on all attached displays.

```
var externalContentProtectionStatus: AVExternalContentProtectionStatus { get }
```

## Discussion

This property isn’t key-value observable. Instead, use the [`contentKeySession(_:externalProtectionStatusDidChangeFor:)`](/documentation/AVFoundation/AVContentKeySessionDelegate/contentKeySession(_:externalProtectionStatusDidChangeFor:)) delegate method to monitor changes to this value.
