What is a dead man's switch in simple terms?

It is a mechanism that releases information automatically if you stop responding or checking in. In a digital-legacy context, it delivers your accounts, documents, and final wishes to chosen people if something happens to you.

Are dead man's switches reliable?

Simple timer-based switches are prone to false triggers, such as a missed check-in during travel or a hospital stay. A reliable design adds human confirmation from people you trust and a stand-down path, so it only fires when something has genuinely happened.

Can a dead man's switch trigger by accident?

A pure timer can, which is the main risk of DIY versions. Break Glass avoids this by requiring the family and friends you chose to confirm the event, and any one of them can halt the process with a single stand-down.

Do I need a dead man's switch?

It is worth having if you hold accounts, documents, or crypto your family could not otherwise reach, or if you want final instructions to arrive at the right time. Break Glass provides this with per-item encryption and human confirmation.

What Is a Dead Man's Switch, and Do You Need One?

A dead man's switch is a mechanism that triggers automatically if the person responsible for it stops responding. The term comes from machinery: a control that stops a train or a saw the moment the operator lets go. Applied to your digital life, a dead man's switch releases specific information to specific people if you can no longer check in yourself.

The idea is sound. Most do-it-yourself versions are not. Here is how they actually work and where they go wrong.

How a basic dead man's switch works

The simplest design is a timer:

The system pings you on a schedule ("are you still there?").
You check in to reset the timer.
If you miss enough check-ins, it assumes the worst and releases your information.

Simple, and dangerous. A pure timer cannot tell the difference between "something happened to me" and "I was on a long trip with no signal." That gap is where DIY switches cause real harm.

Where DIY switches go wrong

False triggers. A missed check-in during a vacation, hospital stay, or dead phone can release your most sensitive information while you are perfectly fine.
No human judgment. A timer has no way to verify the event. It just counts down.
Weak security. Home-built scripts often store the payload in plain text or on a single server that, if breached, hands an attacker everything.
No graceful recovery. Once a bad trigger fires, there is often no way to pull it back.

A switch you cannot trust not to misfire is worse than no switch at all.

What a trustworthy switch looks like

A dead man's switch you can actually rely on adds human confirmation and real encryption:

People, not just timers. The release is confirmed by family and friends you chose, so a real person verifies the event before anything opens.
A stand-down path. A single "they're fine" from any verifier halts the whole process, and you are warned the moment it starts.
Per-item encryption. Everything is encrypted, each item under its own key, so a breach yields scrambled noise.
Selective delivery. Different people receive different things, not one all-or-nothing dump.

Do you actually need one?

You are a good candidate if you have:

Accounts or documents your family would struggle to find or access
Cryptocurrency or digital assets with no recovery path
Dependents who would face real hardship without your instructions
A wish to leave letters or final instructions that reach the right people at the right time

How Break Glass does it safely

Break Glass is a dead man's switch built around human confirmation instead of a blind timer. Your vault releases only when the people you trust confirm something has happened, any verifier can stand it down, and every item is encrypted under its own key that even our staff cannot read.

Set up your vault in about five minutes.
