You can set an account pin for easier security verification when calling Server Australia for a support request.
First, log into your MySAU portal at https://www.mysau.com.au
Next, Click on Account
On the new page, select Update your profile.
Finally, under Other Details, set an account pin in the text field using alphanumerics, and special characters (0-9, a-z, A-Z, !@# and so on...), then save the pin by clicking Update Profile.
Once set this pin can be quoted for authorisation when calling for phone support.
