How SMS Security works
Once you’re registered for SMS Security, you’ll receive a unique authorisation code on your mobile when banking online. Simply, enter the code and you're done!
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.
If you don't own a mobile phone, live in a mobile service area or you experience accessibility problems, please call our Internet Banking Support team on 1300 651 656 to discuss your options.
SMS codes
If you receive an SMS code and you’re not logged into online banking, call our security specialists on 1300 651 656 and we'll take care of it.

Help and support
-
When you make a payment to a biller or payee for the first time, you will need an SMS code.
You can pre-authenticate regular payees and billers you’ve saved in NAB Internet Banking, so you’ll only need your password or passcode to make a payment.
If you’re using a different device, you may still need to enter an SMS code.
-
To protect your account from fraud, your daily transfer limit is $5,000 if you’re registered for SMS security.
If you’re not registered it is $2,500.
The daily limit of $2,500 applies to BPAY® Bill payments except payments made to NAB authorised billers.
For answers to your frequently asked questions about daily limits read our simple help guide.

If you don’t have a mobile phone and your landline can accept SMS messages, you can register your landline instead of a mobile number.
If you’re travelling within Australia, SMS Security will be available in a mobile coverage area.
If you’re overseas, you can send and receive SMS if your handset and SIM card allow global roaming and the country you are in operates via a compatible network. Please check with your mobile phone service provider.

To protect you when you make Pay anyone payments, you may be asked to confirm a transaction with a SMS Security Code – even if you’ve paid that payee before.
