What is 'two-factor authentication' and 'OnlineCode'?

To protect your security, we often need to confirm who you are before giving you access to your accounts. A two-factor authentication process uses two 'factors':

  • Something you know e.g. your customer number and password, and
  • Something you have e.g. an object or device, such as your mobile phone in this case.

OnlineCode is a 'two-factor authentication' process for National Bank Online Banking. It works by sending a unique 8-digit 'single use' code to your mobile phone when you begin to use an Online Banking function for which OnlineCode applies. The 8-digit code is valid for your entire Online Banking session, enabling you to do multiple transactions.

How do I register for OnlineCode?

To register for this service you need a TXT capable mobile phone. Log In to Online Banking, go to 'My Details & Services' page, click on the 'OnlineCode Registration' link and follow the prompts.

What features of Online Banking can OnlineCode be used with?

You can use OnlineCode for creating and amending Automatic Payments, creating bill payees, Bill Payments, One-off Payments and Tax Payments. It can also be used for changing your contact details, email preferences and Online Banking password.

When will OnlineCode be required?

Registration and use is compulsory if you want to make payments larger than $10,000 or send money overseas. You can opt to use OnlineCode for all your transactions, setting up payees, and changing your Online Banking preferences.
