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.

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.
