# VSAccountManagerDelegate

The methods you use to respond to authentication view controller requests.

```
protocol VSAccountManagerDelegate : NSObjectProtocol
```

## Overview

Use the [`VSAccountManagerDelegate`](/documentation/VideoSubscriberAccount/VSAccountManagerDelegate) methods to aid in displaying and dismissing authentication view controllers.

If the person isn’t authenticated when your app calls [`enqueue(_:completionHandler:)`](/documentation/VideoSubscriberAccount/VSAccountManager/enqueue(_:completionHandler:)) with [`isInterruptionAllowed`](/documentation/VideoSubscriberAccount/VSAccountMetadataRequest/isInterruptionAllowed) set to <doc://com.apple.documentation/documentation/Swift/true>, the system sends an authentication view controller to the delegate in the [`accountManager(_:present:)`](/documentation/VideoSubscriberAccount/VSAccountManagerDelegate/accountManager(_:present:)) method for your app to present to them.

## Topics

### Displaying Authentication Views

[`accountManager(_:present:)`](/documentation/VideoSubscriberAccount/VSAccountManagerDelegate/accountManager(_:present:))

Tells the delegate to present an authentication view controller.

### Dismissing Authentication Views

[`accountManager(_:dismiss:)`](/documentation/VideoSubscriberAccount/VSAccountManagerDelegate/accountManager(_:dismiss:))

Tells the delegate to dismiss an authentication view controller.

### Supporting Degradation Scenarios

[`accountManager(_:shouldAuthenticateAccountProviderWithIdentifier:)`](/documentation/VideoSubscriberAccount/VSAccountManagerDelegate/accountManager(_:shouldAuthenticateAccountProviderWithIdentifier:))

Asks the delegate whether to authenticate the user with the selected provider.
