COLDCARD weak random number security incident: mnemonics using Passphrase can avoid the attack
SlowMist's Cosine stated on the X platform that in the COLDCARD hardware wallet weak random number security incident, if the mnemonic uses a Passphrase, the attack can be avoided. The Passphrase is not the wallet unlock PIN code, but a password specifically set for the mnemonic, and this mechanism is supported by mainstream hardware wallets.
