NetCode Security

Over one million Bank customers now using NetCode security

At the Commonwealth Bank, we’re committed to making your online banking experience the best it can be. Part of that commitment is providing you with a secure banking environment to keep your valuable personal information and financial details safe, wherever and however you choose to use NetBank.

One of our security measures is NetCode, a free service that protects your information using world-class technology. NetCode uses SMS messages, CommBank App notifications or a security token to send you an one-time security code whenever you make certain transactions. This adds an extra level of security to your transactions, and also lets you know if anyone else is attempting to access your account or your details.
