# enableCredentialSharingMode(withExtendedPANId:completion:)

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

## Declaration

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

```swift
func enableCredentialSharingModeWithExtendedPANId(extendedPANId xpanId: Data) async throws
```

## 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, an alert appears asking for user permission to access credentials. The one-time admin code is displayed internally via an alert; it is not returned to the caller. /// - Parameters: extendedPANID: The extended PAN identifier of the Thread network. completion: The completion handler the framework calls after the user acknowledges the alert. The error parameter is nil on success, or non-nil if credential sharing mode could not be enabled. 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 enableCredentialSharingModeWithExtendedPANId(extendedPANId: Data, completion: @escaping (Error?) -> Void)

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