Important Notice** : Hi! To help keep your services secure, we’ve introduced Multi-Factor Authentication (MFA) for all users of the Optus Customer Management Interface (CMI). Between 12/11/2025 – 30/01/2026, all existing CMI users will be prompted to set up their account for MFA via a simple self-enrolment process the next time you log in. Please see
here for a detailed guide on how to enable MFA on your account.
