Never turn recovery material into a support credential

Deep technical lesson
01
Mental model

A recovery phrase or private key is not a password reset token. Anyone who receives it can usually reconstruct signing authority. Legitimate support workflows should never require it, and security processes should assume any disclosed recovery material is permanently compromised.

This concept matters because Never type a seed phrase into a website presented as support.

Seed phrases deterministically reconstruct signing authority and therefore cannot be scoped like a password reset token.

02
What actually happens

Identify whether the workflow requests recovery words or raw signing material.

At protocol and execution level, inspect seed phrase and derived key and signer and backup and compromise. Protocol identifiers remain untranslated because they are part of the technical payload.

seed phrase

root recovery secret

derived key

account-specific authority

signer

uses key without exposing it

backup

offline recovery copy

compromise

authority must be migrated

03
Failure surface

Entering a seed into a support portal gives the requester durable authority over all derived wallets.

The practical consequence is that A leaked seed cannot be made secret again. Unknown is not equivalent to safe.

  • seed typed into website
  • seed photographed/cloud-synced
  • support asks for recovery words
  • same seed used in insecure environment
  • suspected disclosure without migration
04
Decision standard

Never disclose; if already entered, migrate assets from a known-clean environment.

The practical consequence is that A leaked seed cannot be made secret again.

Escalate when evidence is contradictory, incomplete or the consequence exceeds routine policy.

05
Verification procedure

Verify the request through independent evidence before irreversible authorization.

  1. 01

    classify recovery material

  2. 02

    remove online copies

  3. 03

    verify signer never exports secrets

  4. 04

    design recovery test

  5. 05

    migrate assets after suspected exposure

06
Required analyst output

Record the facts, assumptions, unknowns and decision so another analyst can reproduce the review.

Never type a seed phrase into a website presented as support. and Move assets to new keys after suspected disclosure.

Analyst task

Before answering the checkpoint, identify the authority being granted, the trust boundary that can fail, and the consequence that becomes irreversible.

Evidence map

Organize before you decide

Separate identity, authority, execution and context before reaching a security decision.

01
Identity

Who or what is requesting, receiving or representing authority?

originwallet-helpdesk.io
support Contactunsolicited
02
Authority

What capability can be granted, retained or exercised?

03
Execution

What will the payload, route or system actually do?

04
Context

Which surrounding facts can materially change the decision?

Analyst notebook

Build your evidence memo

Local-only learning record

Record your reasoning before the checkpoint. Finish with an explicit decision or next action. Notes stay on this device.

LOCAL STORAGE
Field exercise

Develop all three sections before completion.

Treat seed phrases and private keys as signing authority, not as support credentials or cloud data.
