3D Secure is a security protocol used by Westpac to provide an extra layer of verification for online card transactions. When you shop at participating merchants, the system may ask you to verify the purchase, ensuring that you are the person authorizing the transaction. This process helps prevent unauthorized card usage by confirming your identity during the checkout flow.
Most transactions are verified through the Westpac mobile app or an SMS code sent to your registered mobile number. Because this step occurs in real-time, it is helpful to have your mobile device nearby when shopping online. If you are not prompted for verification, the merchant may not require 3D Secure for that specific transaction.

How to Complete Payment Verification
When you encounter a 3D Secure prompt during an online purchase, follow these steps to securely authorize the transaction:
- Proceed to checkout on the merchant website and enter your card details.
- If the transaction requires verification, a Westpac screen will appear or you will receive a push notification on your mobile device.
- Open the Westpac app if prompted or check your mobile messages for the secure code.
- Review the transaction details—such as the merchant name and amount—displayed in the verification window.
- Confirm the transaction within the app or enter the SMS code on the merchant’s secure payment page.
Once you confirm, the merchant system receives the authorization and completes the checkout process.
Troubleshooting Verification Issues
MFA and Login Issues: If you do not receive an SMS verification code, check that your signal strength is adequate and that you haven't blocked incoming SMS from short-code numbers. If the code still doesn't arrive, try requesting a new code via the payment screen or ensure your mobile number is up-to-date in your banking profile.
Browser or App Errors: If the 3D Secure verification window fails to load, try disabling browser extensions like ad-blockers, which can occasionally interfere with pop-up windows. If the Westpac app doesn't show a notification, manually open the app and look for a pending authorization request in your dashboard.
Locked Access: If you enter the wrong verification details multiple times, the system may temporarily lock your card for security. In this situation, you will need to contact the support team to verify your identity and unlock your ability to make online purchases.
Pro-Tip: To avoid delays during checkout, ensure your mobile device has "Push Notifications" enabled for the Westpac app. This allows the authorization request to appear on your screen as soon as you hit "pay," making the process faster and more reliable than waiting for an SMS code.
Frequently Asked Questions
Q: Why was I not asked to verify my payment with 3D Secure?
Not every merchant uses 3D Secure technology, and some lower-risk or smaller transactions may not trigger the verification process. The system uses risk-based logic to decide when an extra check is needed. If you are concerned about a transaction, you can check your 'Transaction History' in the app to ensure all charges are accurate, or contact the bank if you see a payment you don't recognize.
Q: What should I do if I get a verification prompt for a payment I didn't make?
If you receive a prompt for a transaction you did not initiate, select 'Decline' or 'Cancel' immediately in the verification window. This prevents the transaction from going through and indicates a possible unauthorized attempt to use your card details. Follow this by locking your card in the app and calling the bank's fraud support line to report the issue and request a replacement card.
