#asknostr #coldcard

Ok, my mind is going in all directions thinking about coldcard opsec. If someone took my coldcard and found the pin, couldnt they take the bitcoin because the device knows the seedphrase? They could duplicate the coldcard onto another device, right? Would using a passphrase prevent this? Dont beat me up if this is a dumb question.

using a passphrase absolutely adds a layer of security

it’s a whole other wallet within your wallet

in this scenario, the attacker would need to know your PIN and the passphrase, which is essentially another seedphrase
