Does Optus support 2FA?

How to enable 2FA on Optus

1. Sign in to your Optus account.
2. Open Account settings → Security (the exact path varies; see the official docs link above).
3. Choose your preferred method from the list — TOTP and hardware keys are the recommended options.
4. Save the recovery codes somewhere safe — they're your last resort if you lose your authenticator and your hardware keys.

Sharing Optus 2FA with a team (with Kaito)

Kaito gives you a vault for shared TOTP and a real-time inbox for shared SMS, with per-token group permissions and an audit log on every code view. To share Optus access with your team:

1. In Kaito, go to Tokens → New and add the Optus 2FA seed (or scan the QR).
2. Permission the token to a group: code-only for most teammates, full-seed only for the admins who would handle rotation.
3. Optus only supports SMS 2FA. Provision a Kaito SMS number and use the service's "phone number on file" setting to point verifications at it. Codes will stream to whoever you've authorized.
4. Stream the audit log to your SIEM if you want a complete record of which team members generated codes for Optus and when.

Note: Optus's terms on account sharing are unclear or grey-area. Many teams share access in practice; doing so via Kaito gives you a clean audit trail if it ever becomes a question.
