Register for SMS Security

What is SMS Security?

SMS Security is our free online security service that provides extra protection when you use NAB Internet Banking or the NAB app.

SMS Security provides more protection online for:

• updating your personal details
• transactions to non-linked NAB accounts or other financial institutions, subject to our security assessment 
• authorising certain new billers and payees
• activating your NAB Visa Debit card
• setting and resetting your NAB Visa Debit or credit card PIN
• linking your card to a digital wallet
• resetting your password
• confirmation of:
  • large transfers if you’ve increased your limit
  • international payments
  • data sharing with accredited third parties.

Make sure you also use trusted security software and strong password management.

SMS Security and push notifications

When logging in to NAB Internet Banking or the NAB app from a new device, you may receive a security code via SMS or a push notification (if enabled). 

You won’t receive an SMS if a push notification is sent.

For a more secure way to receive security codes, we recommend enabling push notifications.

Never share your security code with anyone. We’ll only ask you to share your code with us when you call NAB.

How SMS Security works

• If your mobile number is registered with us, you’ll be automatically registered for SMS Security when you set up NAB Internet Banking.
• You can’t request SMS or push notifications. These are sent depending on our security assessment and if enabled.
• If you’re travelling within Australia, SMS Security will be available in mobile coverage areas.
• If you’re overseas, you can send and receive SMS if:
  • your handset and SIM card allow global roaming
  • the country you are in operates in a compatible network.

        To find out more, check with your mobile phone service provider.

• If your NAB ID was set up under a business profile, you can only register for SMS Security through NAB Internet Banking.
