What is open banking?

Open banking is a service that gives you greater access to and control of information relating to your banking products and services.

You can opt into the service to share banking information between accredited third parties. This makes it easier for you to manage, compare and switch banking products and services.

Open banking is part of new legislation passed by the Australian Government in 2019 called Consumer Data Right (CDR), opens in new window. The aim of the legislation is to increase competition between major banks, other financial institutions and accredited third parties.

Australia’s banking sector is the first to apply the CDR legislation, but the energy and telecommunications sectors will follow.

To find out who is accredited by the ACCC to receive data through open banking, take a look at the Australian Competition and Consumer Commission, opens in new window website.

Types of information you can share

Once you have opted-in to open banking, you can securely share your account summary, balances and transaction history for eligible personal and business banking products such as:

  • credit or debit cards
  • term deposits
  • transaction and savings accounts
  • home loans (mortgages)
  • personal loans
  • business loans.

How to share your data

Open banking is an opt-in process. This is how it works.

Agree to share information with a third party

To provide you with a new or improved service, an accredited third party may ask you to share your banking information with them.

They’ll tell you what data they need, and how long they want you to share it for. This may be once-off, or ongoing data sharing for up to 12 months.

Choose which information to share

To share this data, you’ll be redirected to NAB. Follow the prompts that appear on the screen.

  1.  Enter your NAB Identification Number (NIN).
  2. A one-time password will be sent to your SMS security registered phone number. You’ll never be asked to enter your NAB Internet Banking password to share your data.
  3. Enter this one-time password and follow the prompts to confirm what data you’d like to share.
  4. We’ll share your data with that organisation using a secure connection.

Is open banking safe to use?

Yes, there are strict rules and security protocols in place to protect your information.

Strict accreditation criteria

To request access to your data through open banking, third parties must be accredited by the Australian Competition and Consumer Commission (ACCC). They have set strict accreditation criteria, as well as privacy and information security standards.

One-time password verification

You’ll never need to give your NAB banking password to a third party. If you choose to share your banking data with an accredited open banking participant, a one-time password will be sent to you via SMS to your security-registered phone number to help identify you.

Secure transmission process

Once you have been identified, your data will be transmitted to the third party through a secure connection. This connection is governed by strict terms and conditions defined by the ACCC on how your data must be secured.

  • Open banking is available to eligible:

    • single account holders
    • sole traders
    • joint account holders where there are no more than 2 account holders.
    • all authorised users on individually owned accounts who are nominated for NAB Internet Banking access (via the Internet Banking and Telephone Banking Authorised User Nomination form)
    • all authorised users on business owned accounts who are nominated for NAB Internet Banking access (via the Internet Banking and Telephone Banking Authorised User Nomination form)
  • Under open banking, the following data can be shared by authorised users: 

    • account list
    • transaction list and details
    • account balances
    • direct debits
    • scheduled payments
    • customer details (only authorised user details will be shared)
    • organisation details including your business ABN, business address and contact details. 
  • Any existing and new nominated authorised users appointed by individual account owners will be able to provide consent to share data in relation to the accounts for which they are authorised.
    Please note that an authorised user can only see and manage consents created by them. If an authorised user creates a consent which includes nominated individual accounts, the individual account owners will also be able to see the consent details related to the nominated accounts in their respective internet banking. 

    Important: 
    If you want to remove an authorised user, it’s your responsibility to tell us to withdraw the nomination of the user.

  • Any existing and new nominated authorised users appointed by your business owners will be able to provide consent to share the data in relation to the accounts for which they are authorised.
    Please note that an authorised user can only see and manage consents created by them. Therefore, if one of your authorised users creates a consent, you will not be able to see this in your internet banking. 

    Important:
    If an authorised user leaves your organisation, it’s your responsibility to direct us to withdraw the nomination of the user.

  • If you decide not to participate in open banking, you will need to remove all current authorisations for the nominated users. If you chose to remove nominated users at this stage, it will result in the users losing access to other internet banking functionality as well. This is a temporary way to manage authorisations for open banking and in future it will provide open banking specific authority to manage data sharing. 

  • Yes, joint account holders where there are no more than two account holders over the age of 18 can share their account summary, balance, transaction history, and personal account information such as mail address, payees, scheduled payments and direct debits for accounts such as:

    • credit or debit cards
    • term deposits
    • transaction and savings accounts
    • personal loans
    • home loans (mortgages).

    This data sharing is also available for single-account owners and sole traders.

  • Giving your NAB Internet Banking password to a third-party breaches NAB's Internet Banking terms and conditions.

    There are different types of data sharing environments, such as screen scraping technology (using your NAB ID number and banking password) versus data sharing in the open banking environment.

    When you use open banking, you won't be asked for your banking password. A one-time password will be sent to your phone instead.

    The open banking environment is a safe and secure way to share your information, and doing it this way doesn't breach NAB's Internet Banking terms and conditions. Both types will coexist for a while, so it's worth being aware of which one you are using.
