## AuthSettings.appVerificationDisabledForTesting property

When set, this property disables app verification for the purpose of testing phone authentication. For this property to take effect, it needs to be set before rendering a reCAPTCHA app verifier. When this is disabled, a mock reCAPTCHA is rendered instead. This is useful for manual testing during development or for automated integration tests.

In order to use this feature, you will need to [whitelist your phone number](https://firebase.google.com/docs/auth/web/phone-auth#test-with-whitelisted-phone-numbers) via the Firebase Console.

The default value is false (app verification is enabled).

```typescript
appVerificationDisabledForTesting: boolean;
