# enableCredentialSharingMode(forExtendedPANID:completion:)

Triggers Credential Share mode on a nearby eligible Apple Border Router (tvOS(27.0)).

## Declaration

```swift
func enableCredentialSharingMode(forExtendedPANID extendedPANID: Data, completion: @escaping @Sendable ((any Error)?) -> Void)
```

```swift
func enableCredentialSharingMode(forExtendedPANID extendedPANID: Data) async throws
```

## Parameters

- `extendedPANID`: The extended PAN identifier of the Thread network.
- `completion`: The completion handler the framework calls once credential sharing mode has started. The error parameter is nil on success, or non-nil if credential sharing mode could not be enabled.

## Discussion

Discussion This method scans for Thread credential sharing capable Apple Border Routers, selects an eligible device, and requests to generate an ephemeral 9-digit code and start credential sharing mode. When you call this method, the ephemeral 9-digit code appears on screen along with a warning message; it is not returned to the caller. note: You can call this method from synchronous code using a completion handler, as shown on this page, or you can call it as an asynchronous method that has the following declarations: // Completion handler form: func enableCredentialSharingMode(forExtendedPANID extendedPANID: Data, completion: @escaping (Error?) -> Void)

// Async form (throws on failure): func enableCredentialSharingMode(forExtendedPANID extendedPANID: Data) async throws For information about concurrency and asynchronous code in Swift, see Calling Objective-C APIs Asynchronously.
