When you’re making a purchase online with a Macquarie credit or debit card, you may receive a pop-up on screen – this is a security measure in place to verify that you are the legitimate cardholder making the transaction. This applies to merchants who are 3D Secure (3DS) enabled. Follow the on-screen prompts to verify your identity using Macquarie Authenticator. Find out more about how to Approve or deny using Macquarie Authenticator.
If you don't have Macquarie Authenticator, a secure code will be sent to your registered mobile number via SMS. Please note: The delivery of SMS notifications to international numbers is not guaranteed. We recommend using an Australian mobile number.
It’s important you ensure your contact details are kept up to date in your account. To change your mobile number please refer to Viewing or updating your details.
