Google Authenticator and Okta Authenticator are available as options when you are travelling overseas and don’t have your Australian mobile SIM card activated to international roaming. Once set up on a device, they can be used in most locations, including when you’re back home in Australia. Please see our guide to help you set-up Google authenticator or Okta Authenticator for Member Online.
If you’d like to receive PIN codes via SMS to an international pre-paid number, please reset your MFA while your Australian number is still active, and then wait until you have access to the new number to re-register for MFA. This will need to be repeated when you return home to restore the Australian number.
