Is MasterPass safe to use?
The card and shipping information in your Westpac MasterPass is stored on Mastercard's secure servers.
Your Westpac Mastercard and Visa card are protected by Mastercard's Zero Liability policy and Visa's Zero Liability policy, respectively. However, as with any confidential information, you are also responsible for keeping your information secure and protected at all times. Please refer to the Westpac MasterPass Terms and Conditions for details.
Tip: You can add an extra layer of security by enabling Mobile Verification in your Preferences. During checkout from your computer, after you've selected your card and shipping address, we'll send a text message with a 4-digit verification code to your mobile phone; enter that one-time-use verification code and checkout is complete.
