The duress PIN on the Blockstream Jade Plus is a security feature that lets you set an alternate PIN to protect your Bitcoin in threatening situations.

Unlike your regular PIN, entering the duress PIN wipes the wallet’s encrypted data, displaying an “Internal Error” to make the device appear broken.

This is ideal for scenarios where someone forces you to unlock your wallet, allowing you to comply while keeping your funds safe.

(recoverable later with your backup phrase, as long as it’s securely stored)
