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 Action. 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 every time you open the Westpac Action. You can interact with the Westpac Action for up to 10 minutes without needing to provide the passcode again.

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 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 the upper right icon.
  3. Search for ‘Westpac’.
  4. Select the ‘Westpac Action’.
  5. Tap ‘unlink’.


Tap ‘link’ to link the Westpac Action again and create a new 4-digit passcode when prompted.
