Pass-phrases can provide a reasonable-level of defense in scenarios where plausible-deniability is effective, such as at border-crossings & for financial-privacy… So, use it for that and other purposes…

Pass-phrases SUCK for defending against physical-attacks !

You can not keep secrets when someone is hurting you !

Can you deceive or resist the attacker?

trick question!

— how you will respond in such an extreme situation is unknowable!…

and it’s stressful — if this is your perfunctory plan…

“everyone has a plan,

until they get hit in the face”

— Mike Tyson

secrets are also antithetical to the open-source approach

security by obscurity

Andreas Antonopoulos, from 30 Aug 2018

“security by obscurity — relying on the fact that people don’t know……is the weakest form of security…”

Unfortunately, this dangerous advise is common from leaders like SatoshiLabs, nvk and Pamela Morgan

Bach’s non-sequitur rationale

actually, they COMPOUND the damage, NOT “limit” it…

link to nvk’s bad advise, pictured above.

Not only does this provide a false sense of security,…

the irony of bad advise

Furthermore, not only is this dangerous advise for Hodlers, but it also incentives Attackers to beat and torture you — because they know that the industry-standard-practice is to simply keep a secret !

it also, incentivizes attempts — because there are big pay-offs if saving accounts are simply hidden with a secret word…

Collateral Damage

since “duress” pass-phrases are the industry-standard-practice today,

Attackers will assume that most people are employing this defense…

so, even if you aren’t using them —

“duress” pass-phrases are putting you in danger !

to summarize —

BEFORE — they incentivize attacks !

DURING — they incentivize torture !

AFTER — you lose all your bitcoin !…

Check your friends !

— because this foolish strategy is ubiquitous!

play on classic wrench cartoon

Bonus !

  • Pass-phrases can also be used to designate heir’s wallets in your Inheritance plan…

i’m so happy to report that nvk agrees —

waiting for coldCard’s site to update…
