When only one person knows how the business works

In plain terms

You decide how often you check in. You write the instructions your team, partners, or family would need if you could not explain things yourself. You choose who receives what. While you keep checking in, nothing is sent. If you go silent long enough, the system delivers what you prepared.

We cover other practical examples in practical uses for a dead man's switch.

When one person carries the operating context

In many small businesses, one person quietly becomes the map. They know which account pays payroll, which bank requires a hardware key, how invoices are approved, where contracts live, how the password manager is organized, which vendors matter, and what can wait until next week. If they are in the hospital or otherwise unable to respond, the problem is not just access. It is knowing what to do in what order.

Why not share everything now?

Permanent copies of credentials and approval details create their own risk. A dead man's switch lets you prepare the handoff without exposing everything early. The information stays encrypted until missed check-ins and a grace period make it clear that silence is a real continuity event, not a busy day.

What to pass on

Focus on the first decisions and access paths someone would need to keep the business stable.

• How to access the password manager, 2FA backups, hardware keys, and key devices
• Which bank, payroll, accounting, and payment accounts matter first
• What can be paid or paused immediately, and who can authorize urgent payments
• Where contracts, insurance, tax records, runbooks, and vendor docs live
• Which customers, vendors, accountant, lawyer, bank, or MSP should hear first
• How support inboxes, incidents, refunds, or status updates should be handled
• A short "first 24 hours" and "first week" checklist in the right order

Keeping customers safe and the business alive

The goal is continuity under stress. A prepared handoff can help the next person avoid reckless guesses, pause risky changes, keep payroll and critical vendors moving, reassure customers, and protect systems while leadership figures out the bigger picture. That is contingency planning in human form.
