## Modules to Import

```ts
import { accountManager } from '@kit.MDMKit';
```

## accountManager.disallowAddLocalAccount

disallowAddLocalAccount(admin: Want, disallow: boolean, callback: AsyncCallback<void>): void

Disallows a device administrator application to create local user accounts. This API uses an asynchronous callback to return the result.

**Required permissions**: ohos.permission.ENTERPRISE_SET_ACCOUNT_POLICY

**System capability**: SystemCapability.Customization.EnterpriseDeviceManager



**Parameters**

| Name     | Type                                      | Mandatory  | Description                      |
| -------- | ---------------------------------------- | ---- | ------------------------------- |
| admin    | [Want](../apis-ability-kit/js-apis-app-ability-want.md)     | Yes   | Device administrator application.                 |
| disallow    | boolean     | Yes   | Whether to forbid the creation of local user accounts. The value **true** means to forbid the creation of local user accounts, and the value **false** means the opposite.                 |
| callback | AsyncCallback<void>            | Yes   | Callback used to return the result. If the operation is successful, **err** is **null**. Otherwise, **err** is an error object.      |

**Error codes**

| ------- | ---------------------------------------------------------------------------- |
| 9200001 | The application is not an administrator application of the device. |
| 9200002 | The administrator application does not have permission to manage the device. |

});
```

## accountManager.disallowAddLocalAccount
