Bank online with confidence
SMS Security is our free and easy online security service. With SMS Security, you'll get extra security protection and additional features when you use the NAB app or NAB Internet Banking. These include:
- Updating your personal details
- Activating your NAB Visa Debit card
- Setting and resetting your NAB Visa Debit or Credit Card PIN
- Resetting your password
- Authorising new billers and payees
- Confirming large transfers if you’ve increased your limit
- Confirming international payments .
How SMS Security works
We’ll send you a unique authorisation code to your mobile phone when you use an SMS Security feature through NAB Internet Banking or NAB app. Simply enter the code and you're done! This way, your online accounts stay secure even if your NAB ID and password fall into the wrong hands.
And if someone attempts an unauthorised payment from your account, we'll alert you via SMS. If this happens, just call our security specialists on 1300 651 656 and we'll take care of it – now that's peace of mind.
An authorisation limit - no longer available
To better protect you when making online payments, the $300 SMS Security Authorisation Limit (which previously enabled you to transfer funds for small amounts up to $300 without the need to receive and enter a SMS authorisation code for each payment) is no longer available. This means you may now be asked to confirm a transaction with a SMS Security Code – even if you have paid that payee before.
