How to enable 2FA on AT&T
- Sign in to your AT&T account.
- Open Account settings → Security (the exact path varies; see the official docs link above).
- Choose your preferred method from the list — TOTP and hardware keys are the recommended options.
- Save the recovery codes somewhere safe — they're your last resort if you lose your authenticator and your hardware keys.
Sharing AT&T 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 AT&T access with your team:
- In Kaito, go to Tokens → New and add the AT&T 2FA seed (or scan the QR).
- Permission the token to a group:
code-onlyfor most teammates,full-seedonly for the admins who would handle rotation. - AT&T 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.
- Stream the audit log to your SIEM if you want a complete record of which team members generated codes for AT&T and when.
Note: AT&T'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.
