What is a dead man’s switch? A simple, practical explanation

A dead man’s switch is a system that triggers an action only if you stop checking in. Here’s how it works — and what to look for in a safe setup.

Definition (in plain English)

In digital terms, it’s a workflow: you periodically confirm you’re okay; if you don’t, the system escalates reminders and eventually delivers messages or instructions.

How it usually works (4 steps)

  1. You create a message and choose recipients.
  2. The service sends periodic check‑ins (“Are you still here?”).
  3. If you miss enough check‑ins, a waiting period starts (with multiple reminders).
  4. Optional: a trusted contact verifies before delivery; otherwise delivery happens after the waiting period.

When people use it

  • Personal messages: goodbye letters, advice, memories.
  • Digital legacy: instructions for accounts, devices, and subscriptions.
  • Business continuity: critical access and handover info for partners.

What to look for in a reliable setup

The most important thing isn’t fancy features — it’s reducing accidental delivery and making sure the right person gets the right info.

  • Multiple reminders and a clear waiting period (not a single missed email).
  • A way to minimize false triggers (deliverability, easy confirmation).
  • Optional trusted contacts or other safeguards.
  • A clear continuity plan (what happens if the service shuts down).
