Updating Your CommBank Security Credentials
Maintaining strong login credentials is a standard part of keeping your finances secure. Whether you are performing a regular security update or you suspect your password has been compromised, changing your CommBank password can be managed through the bank's digital platforms. You do not need to visit a branch to make this change, provided you have access to your registered mobile device to verify the request.
The process differs slightly depending on whether you are logged in or have forgotten your details. If you know your current password, you can update it through the settings menu. If you are locked out, the bank provides a specific recovery flow that relies on verifying your identity using your CommBank card and your registered mobile phone number.
Key Details for Updating Your Credentials
| Category | Details |
|---|---|
| Available Methods | CommBank app, NetBank (online), or phone support. |

A client can change the password for access to Internet Banking in the following way:

- create a new password and follow the prompts
Troubleshooting Login and Access Issues
MFA / Login Issues
If you do not receive the NetCode SMS required to verify your password change, this is often caused by temporary mobile network delays. A simple fix is to toggle your phone’s airplane mode on and off to refresh the connection to your service provider. If the code still does not arrive, check that your registered mobile number is current; if it is not, you will need to call the bank to update your contact details.
Browser or App Errors
Sometimes the screen may freeze or fail to save your new password. This generally happens when the browser cache is cluttered or the app version is outdated. Try clearing your browser’s cache or ensuring your app is updated to the latest version in the app store. If the problem persists, try using a different web browser or device to complete the update.
Locked Account / ID Issues
Entering an incorrect password multiple times will lock your account to protect against unauthorized access. If you are locked out, you cannot update your password via standard settings. Instead, use the 'I forgot my password' link on the login page. This process will require your CommBank card number and PIN to verify your identity before allowing you to set a new password.
Pro-Tip: Using a password manager is a more effective way to maintain security than trying to memorize complex passwords. Most reputable password managers allow you to generate and store unique, high-strength passwords for your banking profile, reducing the risk of using weak or reused credentials across different services.
Frequently Asked Questions
What if I don't know my current password?
If you cannot remember your password, you do not need to change it through the 'Settings' menu. Instead, navigate to the main login screen on the app or website and select the 'I forgot my password' option. The system will then guide you through a verification process that uses your CommBank card details and PIN. Note that if you do not have your physical card, you will not be able to complete this self-service reset and will need to contact the bank's support team for alternative verification.
Why was my new password rejected?
The system has specific complexity requirements to ensure your account remains protected against automated guessing attempts. If your password is rejected, it likely does not meet the criteria, such as including a mix of uppercase letters, numbers, or specific character lengths. The bank typically displays the exact requirements on the change password screen. Review these guidelines and ensure your new entry matches every rule, then attempt to save it again.
