Protecting your digital banking profile requires a multi-layered approach to security. Commonwealth Bank (CommBank) offers several tools designed to confirm your identity and prevent unauthorized access to your funds, including biometric login methods, multi-factor authentication (NetCode), and real-time fraud monitoring alerts.
Engaging with these security options helps provide a robust defense against potential cyber threats. By configuring these settings correctly within your banking profile, you establish clear controls over who can access your accounts and approve transactions, adding a necessary barrier between your personal information and external risks.

Frequently Asked Questions
Why am I getting a security prompt for a login I did not initiate?
The bank’s security system monitors for unrecognized device logins or unusual IP addresses. If you receive a prompt or a NetCode when you are not actively logging in, this suggests someone else may have your credentials. The system pauses the request, requiring your physical authorization to proceed. Do not share this code. Your practical next step is to log into NetBank from a secure device, change your password, and call the fraud line to report the suspicious activity.
What should I do if I lose my phone and can no longer receive 2FA codes?
NetCode is linked to your registered device, meaning that without it, you lose your primary method of confirming high-risk actions. The system treats the phone as a key; if the key is missing, you cannot bypass the security check without bank intervention. This prevents others from accessing your account if they find your phone. Your practical next step is to contact the bank immediately to report the device as lost, which allows them to disable the NetCode link on that phone and assist you in securing your profile.
