How SMS Security works

Using SMS Security means your online accounts stay secure even if your NAB ID and password fall into the wrong hands. If someone attempts an unauthorised payment from your account, we'll alert you via SMS.

Important: When creating a Pay anyone payment in NAB Internet Banking, you may receive a security code via a push notification. You may also receive a security code via push notification when logging in from a new device. Enable push notifications for a more secure way to receive security codes.
