Key Takeaways
- Scenario 1256 is MFA RESET vs KEEP — not HELP, CANCEL/STOP, teammate YES, card UPDATE, lockout, go-live, PAY/PLAN, API-key, export, SSO DNS, incident ACK, sandbox, webhook replay, SCIM, domain, IP allowlist, maintenance, data-residency, SAML ROTATE, or DSR START.
- A stolen-phone ticket that reads KEEP after the admin already reset tokens is an outage, not a cautious ops choice.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free is 300 SMS lifetime, 1 device. Developer is 25,000 SMS per year.
- Starter is 2 devices; the on-call spare still counts.
- Hold product-launch CSV until RESET/KEEP drains.
- Canary the inbox SIM at 08:40, not at Monday’s weekly digest.
Summary
Scenario 1256 is a stolen-authenticator ticket: prompt RESET or KEEP at 09:00, parse only those verbs, launch CSV held until replies drain. Service pricing is based on device count and total SMS sent through the gateway. You need a working Android phone with a SIM and SMS credit from your mobile operator. Operator message costs are yours—we do not sell carrier SMS balance.
If tokens already rotated and the admin texted KEEP into a full queue, you did not pause. You split-brained MFA.
Not a CodeCanyon “SaaS SMS” pack. Device meters apply — Twilio vs Android SMS gateway.

Context
Identity proof lands at 08:50. Tokens must not reset on “OK.” Growth still wants a changelog CSV.
Free (300 SMS lifetime) is a rehearsal tenant. Developer is 25,000 SMS per year.
Core scenario guidance
09:00 is RESET/KEEP, not lockout HELP. Timezone is the admin, not the vendor HQ.
MFA inbox roles
| Role | When | Typical fail |
|---|---|---|
| RESET vs KEEP | 09:00 admin local | Phone on a charger in a locked cage after 08:00 |
| Ambiguous reply | OK / YES / 1 | Treated as RESET without a second confirm |
| Login OTP | Transactional, own pool | Dumped onto the MFA inbox radio |
| Launch / changelog | Held until last RESET/KEEP | Released at 09:00 into inbox SMS |
Cost and ownership
Priced by devices and SMS send volume. You use your own phone and operator SMS credit. The inbox spare is a billed device. Prompt retries burn airtime.
Name a 08:20–11:00 on-call for MFA mornings, not only weekday support.
Operations
08:40 canary. Abort: hold launch CSV, keep login OTP, skip a second “all admins” blast. Do not “resend tenants.”
Security and compliance
Short verbs. No recovery codes in SMS. Authenticate webhook hooks. Launch lists are promotional.
Decision guide
Ship when 08:40 canary is green and RESET/KEEP parse is exact. Delay if the inbox phone sleeps after 08:00. If handsets are forbidden, CPaaS for login OTP.
Checklist
- Inbox SIM paired overnight.
- 08:40 canary.
- RESET/KEEP only — no OK.
- Login OTP isolated.
- Launch CSV held.
- Airtime before 08:20.
- Battery exemptions.
- Admin locale.
- MFA-morning on-call named.
- Device cap includes spare.
Next steps
Review device and SMS volume pricing, device setup, SMS API documentation.
Deep dive: production hardening
Facilities killing USB at 08:10 is an outage at 09:00. Watch inbound keywords, not IdP 200s.
Deep dive: scaling and failure modes
Multi-region MFA weeks add devices before inventing a hidden unlimited-handset SKU. Raise OEM ceilings; fair-use remains.
Deep dive: integration discipline
Idempotency on ticket_id + kind (prompt|reset|keep). MCP is a REST wrapper — live fields in Developer Center.
Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
08:40 MFA drill
Canary. Send KEEP from a staff SIM; confirm no token wipe. Hold launch CSV during the wave.
