Security tips for your CommBiz service

CommBiz security

Your security is extremely important to us. Here are four important tips for keeping your CommBiz service secure.

1.    Keep your user list and Electronic Account Authorities up-to-date

Always ensure that your list of users on your CommBiz service is up-to-date. If users leave your business, make sure they are removed from the CommBiz user list; if they go on extended leave, remember to suspend their access until they return. Ensuring no one except valid users are on your list will help protect you against fraudulent transactions being submitted on your CommBiz Service.

You should also keep your Electronic Account Authorities up-to-date to help ensure that no fraudulent transactions are authorised on your accounts.

2.    Beware of hoax emails

Hoax emails may appear to been sent from the Commonwealth Bank because they have a Commonwealth Bank logo and other CommBiz features, but it is important to be aware that they may not be legitimate.

Things to look out for:

  • Do not provide personal details via email. The Commonwealth Bank will NEVER ask for your personal details in an email, so any such email is a hoax and should be forwarded to and deleted from your inbox.
  • Emails will not contain hyperlinks. Emails that contain links to pages that appear to be CommBiz web pages may actually direct you to malicious websites. We do not insert hyperlinks within emails, so any email purporting to be from the Commonwealth Bank but containing hyperlinks should be forwarded to and deleted from your inbox.

You should always access CommBiz via the web address ‘’.

3.    Keep your virus software up-to-date

Make sure the virus software on your computer is up-to-date. This will ensure no malicious software can be downloaded onto your computer without your knowledge. Most anti-virus software will automatically remind you when it is due to expire, so don’t ignore these warnings. Leaving your computer unprotected for even a short time can be long enough for viruses to get into your system.

4.    Keep your CommBiz token and password secure

Keep your CommBiz token secure at all times, so that no one else can use it to access your CommBiz profile or authorise transactions without your knowledge.

You must also keep you CommBiz password secure by doing the following:

  • If you must write down your password, make sure it is not kept anywhere near your token (do NOT write it on the back of your token).
  • Change your password regularly.
  • Do not set your computer to auto-fill your password.
  • Do not share your password with anyone.
