Make sure you know your FastNet Classic internet banking password. If you don’t know your password, you may be able to reset it on your old device.

Follow these steps to set up the ASB Mobile Banking app on your new phone:

De-register the app on your old phone:

ASB Mobile app: 

  1. Log in to the ASB Mobile app.
  2. Tap the profile icon in the top left corner of the ‘Accounts’ screen.
  3. Tap ‘Settings’, and under ‘Devices’ select ‘Manage devices’.
  4. Select the device you wish to deregister and tap 'Remove device'.

FastNet Classic:

  1. Log in to your FastNet Classic account.
  2. Click on 'Settings' in the top right of the page.
  3. Click on ‘Manage devices’.
  4. Select the device you wish to deregister and click 'Remove device'.
  5. Click 'Remove' to confirm.

Download and register the ASB Mobile Banking app on your new device.

If you’re having trouble registering the app on your new device, uninstall the ASB Mobile Banking app, then install it again and continue with the registration process.
