Mobile authentication

Once you’ve set up your BNZ Mobile Business Banking app, you can use mobile authentication. It works with your user ID, access number and password to provide an extra layer of security, commonly referred to as two-step authentication, to your Internet Banking for Business on desktop.

You can use it anytime authentication is required; most commonly when you log in.

How to use mobile authentication

If you haven’t set up the BNZ Mobile Business Banking app 

  1. Download the BNZ Mobile Business Banking app on Google Play for Android, or the App Store  for iOS.
  2. Open the app and follow the instructions to activate the app on your mobile device. You’ll need your blue NetGuard token, or a valid mobile phone number entered in your Internet Banking for Business settings, and access to your email address.
  3. Log in to Internet Banking for Business on your desktop using your access number, user ID and password. 
  4. When you’re presented with the authentication screen, select Use BNZ Business Banking app. 
  5. Open the Mobile Business Banking app on your mobile device and tap Approve to confirm the request.
