A $5 wrench isn’t the only physical attack you should be thinking about.

There’s a quieter, more dangerous scenario: Someone gains access to your hardware wallet, opens it, extracts sensitive data, then puts it back exactly as it was.

The next time you use it, everything appears normal. But your keys may already be compromised.

Most hardware wallets address this risk with tamper-evident mechanisms, typically stickers or seals that rely on the user noticing a change.

If that signal is missed or misunderstood, the device may continue to be used in a compromised state.

Passport Prime takes a different approach.

It includes active tamper detection that continuously monitors whether the device has been physically opened or modified, or even tried to be.

If tampering is detected, the device automatically erases all sensitive data, including your Master Key.

This process happens immediately. There are no warnings, no prompts, and no way to override it.

The assumption is simple: If the physical integrity of the device is compromised, your keys should no longer exist on it.

Security shouldn’t depend on whether someone notices a broken seal.
