# notAuthenticated

An error indicating that you can’t verify the user’s credentials.

## Declaration

```swift
static var notAuthenticated: NSFileProviderError.Code { get }
```

## Discussion

Discussion If your File Provider extension returns a notAuthenticated error, the system presents an alert to the user. If you have a File Provider UI extension, the system calls your FPUIActionExtensionViewController class’s prepare(forError:) method before displaying the alert.
