const mfaPushChallengePush = new MfaPushChallengePush();
await mfaPushChallengePush.continue();
```
WithRememberOptions}>
**Properties**
Switches to entering the verification code manually
```typescript Example theme={null}
const mfaPushChallengePush = new MfaPushChallengePush();
await mfaPushChallengePush.enterCodeManually();
```
CustomOptions}>
Optional custom options to include with the request
Error[]}>
Retrieves the array of transaction errors from the context, or an empty array if none exist.
An array of error objects from the transaction context.
MfaPushPollingControl}>
**`Utility Feature`**
Starts and manages polling for an MFA push challenge.
Creates a polling session that repeatedly checks the MFA push challenge endpoint
at the specified interval until the challenge is approved or an error occurs.
When the approval condition is met, the provided
[onCompleted](/docs/libraries/acul/js-sdk/Screens/type-aliases/MfaPollingOptions#oncompleted) callback is invoked and
polling stops automatically.
Use the returned [MfaPushPollingControl](/docs/libraries/acul/js-sdk/Screens/interfaces/MfaPushPollingControl) to start, stop, or check the
status of the polling process at any time.
A [MfaPushPollingControl](/docs/libraries/acul/js-sdk/Screens/interfaces/MfaPushPollingControl) instance exposing:
* `startPolling()` — Starts or resumes polling.
* `stopPolling()` — Cancels polling immediately.
* `isRunning()` — Indicates whether polling is currently active.
```ts Example theme={null}
// Start polling every 5 seconds until the push challenge is approved
const control = mfaPushChallengePush.pollingManager({
intervalMs: 5000,
onCompleted: () => mfaPushChallengePush.continue(),
onError: (error) => console.error('Polling error:', error),
});
// Later, cancel polling if needed
control.stopPolling();
```
#### Remarks
* HTTP 429 (rate limit) responses are handled internally: polling automatically
waits until the rate limit resets before retrying.
* Safe to call `startPolling()` multiple times; it has no effect if already running.
