# ASAccountAuthenticationModificationReplacePasswordWithSignInWithAppleRequest

A request to upgrade from using a password to using Sign in with Apple.

```
class ASAccountAuthenticationModificationReplacePasswordWithSignInWithAppleRequest
```

## Overview

Your app uses this class to initiate an upgrade to Sign in with Apple. After creating the request, your app initiates the upgrade process by instantiating an [`ASAccountAuthenticationModificationController`](/documentation/AuthenticationServices/ASAccountAuthenticationModificationController) object and calling [`perform(_:)`](/documentation/AuthenticationServices/ASAccountAuthenticationModificationController/perform(_:)) on it. The system invokes your authentication modification extension to complete the upgrade.
