SW-04 How will authorised staff sign in, hand over responsibility and recover access after a device or access key is lost?

Start here · Questions · Progress · People decide

Why this matters

Relief staff need usable access during long outages, while the service needs a clear record of who can publish, maintain equipment or handle private requests.

What to bring back

Map likely misuse and failure cases, then set out staff roles and device keys from first setup through replacement. Explain offline sign-in, relief access, withdrawal of access and recovery. Check a stolen device, an expired permission, a withdrawn publisher key and an absent administrator against DAT-01.

What we know so far

AI-generated potential answers

For discussion and review · research checked 2026-10-20. These are AI-generated options and transfer assessments. The user's request and research method identify the source of this work. The source catalogue states what the references establish. The decision and approval record retains its own status.

Give staff named roles and individual access, with a practical backup and recorded shift handover. Prepare lost-device and absent-administrator recovery before deployment. Set explicit limits for offline permissions and explain when a disconnected kiosk has yet to receive an access withdrawal.

Named access with rehearsed recovery

AI-generated adaptation of an existing pattern. Compare suitable staff authenticators and recovery arrangements using NIST's event-management guidance. Keep public browsing available as a guest, and rehearse qualified staff replacing a lost credential without exposing another person's account.

Research basis: NIST SP 800-63B-4: authenticator event management.

Short-lived delegated shift credentials

AI-generated future concept. Explore a narrowly scoped temporary credential for an agreed relief shift, with a visible expiry and an independent recovery holder. Test clock uncertainty and delayed withdrawals before accepting it for sensitive actions.

Examples and local differences

  • NIST SP 800-63B-4: authenticator event management: AI transfer assessment: Access includes replacement, invalidation and recovery throughout an authenticator's life. Local difference to check: An island outage introduces delayed revocation information and a smaller roster of available, authorised relief staff.

Evidence to bring back next

  • Rehearse a stolen staff device, an expired permission and a withdrawn publishing credential during internet loss.
  • Agree who actually holds recovery responsibility, its limits and the review required for sensitive actions.
