After you set up two-step verification, you can use the Google Authenticator app to create your verification codes. Get the iPhone version at the App Store or the Android version through Google Play. Google Authenticator isn't available for Windows phones.
Once you have the app, follow these instructions:
- Sign into your Intuit Account and select Sign in & security.
- Select Two-step verification.
- Turn on two-step verification if you haven't already.
- Select Turn on Authenticator app and follow the onscreen instructions.
To disable Google Authenticator, simply disable the two-step verification feature.
