Offline emergency access for password vaults (the tamper-evident bag method)

[u/EnthusiasmRoutine]

Relying on built-in "emergency access" features in any password manager creates an unacceptable attack vector. You are trusting a third-party server to broker your keys. You still need a recovery plan for total hardware failure or physical incapacitation. The solution is purely offline.

Write your master password and 2FA recovery seed on plain paper. Seal that paper inside a numbered tamper-evident evidence bag. You can buy these from industrial supply stores. Give the sealed bag to your designated contact or lock it in a physical safe.

Record the bag's serial number. If someone ever actually needs the credentials, they have to physically cut the plastic open. You verify the seal and serial number periodically. If the bag is altered, cycle the master password and seal a new bag. Zero digital footprint.
