What Is a Dead Man's Switch?

The term comes from locomotive engineering. In trains, a dead man's switch is a pedal the operator must press periodically. If the operator becomes incapacitated and stops pressing it, the train brakes automatically.

The same principle applies to your digital life. A digital dead man's switch works like this:

  • You store important information — passwords, documents, messages, instructions
  • You check in on a regular schedule (daily, weekly, or custom)
  • If you stop checking in beyond a threshold you set, the system assumes something has happened to you
  • Your stored information is automatically delivered to the people you trust

No lawyers, no probate court, no waiting period. Just a simple automated handoff when you need it most.

Why Traditional Estate Planning Isn't Enough

A will tells your family what you want to happen with your assets. But a will doesn't:

  • Give anyone your email password
  • Explain where you stored your life insurance policy
  • Deliver a final message to your children
  • Provide access to your cryptocurrency wallet
  • Tell your spouse how to pay the mortgage

Traditional estate planning handles the legal transfer of property. It doesn't handle the practical, day-to-day information your family needs in the first hours and days after you're gone — when they're grieving and overwhelmed and just need to log into your bank account to pay the electric bill.

How Lazarus Vault's Switch Works

The system is intentionally simple:

1. You Set Your Check-In Schedule

Choose how often you want to check in — daily, weekly, or on a custom interval. This is your heartbeat. As long as you're checking in, nothing happens. Your vault stays locked.

2. You Choose Your Threshold

How many missed check-ins before the switch triggers? The default is 5, but you can adjust it. If you check in daily with a threshold of 5, that means roughly 5 days of silence before delivery. Weekly with a threshold of 5 means about 5 weeks.

3. You Get Reminders

Before anything happens, you get email reminders. If you miss a check-in, you'll get a reminder. If you miss several, you'll get warnings. You always have a chance to check in and reset the clock.

4. Delivery Happens Automatically

If you pass your threshold without checking in, your vault opens. Your files and messages are delivered to the recipients you specified. They get secure links via email with everything you left for them.

Who Needs a Dead Man's Switch?

Short answer: every adult with people who depend on them.

  • Parents — your children need access to insurance, financial accounts, and your wishes
  • Military personnel — the nature of the work carries sudden, unpredictable risk
  • Business owners — someone needs to know how to access accounts, pay vendors, and contact clients
  • People with health conditions — if your condition could impair you suddenly, preparation is essential
  • Anyone living alone — if no one is nearby to manage your affairs, a switch ensures information reaches the right people
  • Journalists, diplomats, and activists — if your work puts you at risk of detention or worse, a switch ensures your evidence and messages reach the world

The Peace of Mind Factor

The real value of a dead man's switch isn't the technology. It's the peace of mind. Once you set it up, you stop worrying about what would happen if something went wrong. You've handled it. You can focus on living.

Setting up a vault takes about 20 minutes. Not setting one up can cost your family months.
