What is my 4-digit passcode and how can I add or change it?

Your 4-digit passcode is the passcode that you created when setting up your Westpac Banking Action for balance requests. This passcode should be different to your banking PIN, as your passcode will need to be said out aloud. If you set up a 4-digit passcode, you will be prompted to provide your passcode when you request to hear your Westpac account balances and recent transactions. You will also be prompted to provide your passcode after you’ve interacted with the Westpac Banking Action for more than 10 minutes.

If you have forgotten your passcode, need to change it or bypassed it at set up and now want to set one up, first unlink the Westpac Banking Action by taking the following steps:

  1. Open the Google Assistant app on your AndroidTM or iPhone device.
  2. Open the ‘Explore’ page by tapping on the compass icon in the top right corner.
  3. Search for ‘Westpac’ in the search box.
  4. Tap on the Westpac search result.
  5. Scroll down and tap on ‘UNLINK’.
  6. Tap on ‘LINK’ to set up again and add payments and account balances.
  7. Follow the simple set up process in Google Assistant.

For payments and transfers (available on Android only) you will need to sign in to the Westpac Mobile Banking app (i.e. using your existing method of passcode or fingerprint) to authorise the payment. Your 4 digit passcode for balance requests will not work for authorising a payment request.
