CommSec has additional security features that provide an extra level of safety to your account. These only take a few minutes to set up on the CommSec website.

• Verbal phone PIN 
  A 6-16 digit numerical PIN that can be used to identify you when you call us.
  
  
• Security questions & answers
  These questions will be used to identify you if you forget your password, or whenever we need extra verification. 
  
  
• Trading password 
  To add an extra level of security to your account, you can use trading password when placing orders via the CommSec website, CommSec Mobile app or CommSec IRESS. This password is different to your login password. 
  
  
• SMS security 
  SMS-based two-factor authentication (2FA) and SMS one-time passwords (OTP) allow you to verify your identity with a code, sent to you via text message. 

Set up these security features on the CommSec website:

1. Log into CommSec

2. Select Settings

3. Go to Security & Passwords section

4. Select the feature you want to enable

CommSec is not liable for any losses resulting from the scams of third parties that have compromised your CommSec credentials.

Verify your calls with CallerCheck

What is CallerCheck? 

CallerCheck allows you to confirm if a caller claiming to be from CommSec or CommBank is legitimate, by triggering a security message in your CommBank app.  

We also use CallerCheck to make sure we’re speaking with the right person when receiving and making calls, before we share any details about your account. 

It’s our preferred way of identifying you over the phone safely.  

CallerCheck is only available for CommSec customers who are CommBank app users. You'll need to have version 4.37 or newer of the CommBank app installed. This feature is not currently available in the CommSec mobile or CommSec Pocket apps.

Create strong, unique passwords

Your banking, social and email accounts contain important information that make up your digital identity. Here’s how to create strong passwords to help keep your information safe.

Creating a secure password

• Use a mix of letters, numbers and symbols 
• Use as many characters as you can – a longer password is harder to decipher 
• Avoid anything that can be easily guessed such as your address or birthday, or common quotes and phrases 
• Consider a passphrase: Similar to a password but instead of creating a string of letters, numbers and symbols, use words that tell a story. For example: MyPetGo@tHa$@PhD. It tells a silly story that’s easy to remember, while increasing the unpredictability of your password and making it difficult to guess 

Password security

• Don't share your passwords with anyone  
• Don’t write your passwords down anywhere 
• Make them unique: reusing a password multiple times makes it less secure – it only requires one breach to compromise all the accounts with the same password 
• If you have many accounts, setting alphanumeric passwords for each can be difficult to remember. In this instance, you may want to consider using passphrases instead 
• When available, enable multi-factor authentication. This adds an additional check to prove your identity. An example might be a code you must enter which is accessed via an authenticator app on your mobile device 

Protect yourself from SMS and email scams

We will never send you an email or SMS asking for banking information like your CommSec Client ID, password, or NetCode; or include a link to login directly from the email or SMS.

Always type commsec.com.au into a browser or use the CommSec app to securely access your investing.

How to check if a message is legitimate:

• When contacted by an unsolicited third party, it's better to be over-cautious. Contact the organisation directly using a phone number from their website (not the email or message) before you reply.
• Hover your mouse over a link to see the destination URL (web address), before clicking it. On a smartphone you can press and hold a link to inspect it. Carefully read these URLs, as they’re often created to look similar to legitimate addresses.

Reduce your risk of being scammed by paying close attention to messages or emails that:

• Aren't quite right – scammers may use similar email addresses (e.g. @combank.com or @Comsec.com) and copy the look and feel of official messages to trick you into thinking a message is legitimate
• Have spelling mistakes and incorrect grammar
• Include an urgent call to action, such as asking you to unlock or verify an account, or log on and pay a traffic infringement notice. They might also contain malicious software (also known as malware) designed to infect your machine and steal data over time

Read all SMS security code messages carefully. Only enter a security code if you'd like to authorise the activity. Never share your security code with anyone, including CommBank & CommSec.
