Our commitment to you 

Customisable controls

Customise different levels of staff access and permissions to support your internal approvals and security policies.

Fraud & scams monitoring

We proactively monitor payments to identify suspicious transactions. In the event of fraud, we're here to help with readily available support and simple, clear processes.

Secure connection

Tokens provide two-factor authentication by generating a one-time password, in addition to your standard log on ID and password.

Scammers are targeting CommBiz users

  • Never share your password with anyone
  • Never click on a link provided by a caller, or in an email or SMS
  • Use an eToken to help secure your connection to CommBiz
  • Set up Electronic Account Authorisers to approve payments, requiring multiple approvers

Securing your CommBiz connection


An eToken is our recommended method of two-factor authentication. It's ready for immediate use once activated in the CommBiz Mobile app – no need to carry a physical device or consider battery life as with physical tokens.
