# revokeAllDeviceSessions

mutation · in the family [Device fleet](/reference/device-fleet/)

## What it does

Kill every live session of one device — the lost-device sweep (usually with suspend).

THE LOST-DEVICE KILL SWITCH: revoke EVERY live device session of one Device in one privileged act (compose with suspendDevice to also block re-exchange); reason REQUIRED — a kill switch never fires silently. Template class A3_DEVICE (hand-derived v30).

## What happens

Requires a reason; answers how many sessions died.
