What is multi-factor authentication?

Multi-factor authentication is a secure way to verify you and your account activity.

A verification will be sent to you as a secure code via SMS to your mobile phone, or if you use Macquarie Authenticator, you have the option to approve via an actionable push notification or a code in the Macquarie Authenticator app.

Do I need to set up multi-factor authentication?

Yes, you’ll need to have multi-factor authentication in place to use both online and mobile banking with Macquarie.
