We’re committed to help keep your banking safe, and you have a role to play too. By working together, we can keep you even safer. Below you can find out what we do, and what you can do, to protect you and your banking.

What we do to help protect your banking

ANZ employs a range of security measures to assist in protecting your personal account information. These measures extend from data encryption to firewalls. Firewalls, together with encryption technology help to provide some of the best security available to keep your personal and account information protected.


Two factor authentication

Two factor authentication is an added security feature comprising two additional steps in the log in process for ANZ Internet Banking:

  • The first lets you know that you’re on the genuine ANZ Internet Banking site with the display of a ‘Site Key’, which includes an image and phrase that you will recognise
  • The second confirms your identity using a number of security questions, which you will need to answer when logging in.


Encryption is turning words and numbers into a coded language. Encryption prevents unauthorised users from being able to change or read your data. ANZ encrypts your personal data using 128-bit SSL (Secure Socket Layer) encryption technology. You can identify whether the Internet Banking session is secure or encrypted when you see <https://> in the address bar.


ANZ employs a firewall to prevent unauthorised access to and from the network. A firewall acts as a barrier between your computer and the Internet. This helps ensure that only authorised data enters and leaves your computer, much like a security guard in front of a building.

Automatic time-outs

Within ANZ Internet Banking and ANZ Pacific App your session can remain unattended for no longer than 15 minutes. After this time, the system automatically "logs off" and ends your session.

If you are not using your device for more than 5 minutes, make sure you "log out" completely from the session so that your banking information cannot be viewed by others.

Further information about the security of your account transactions and enquiries is contained within the ANZ Internet Banking Terms and Conditions.
