Fraud & scams monitoring

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.


NetLock is a USB device that secures your connection to CommBiz every time you log on.

Our security features

Reduce false-billing scams & mistaken payments

NameCheck will prompt you if the account details on a first-time, non-bulk payment don’t look right. This can help protect you from business email compromise scams and mistaken payments.
