Trezor has increased the maximum password length allowed on its hardware wallets in response to security incidents involving Coldcard wallets in July. These changes aim to enhance user protection by allowing stronger passphrases.

According to CoinTelegraph, the July Coldcard attacks saw some users' wallet recovery information compromised, but those with robust passphrases were better shielded from theft. Trezor's move reflects a growing emphasis on password complexity as a critical defense in crypto asset security.

For Japanese investors and traders, who are increasingly integrating hardware wallets into their crypto strategies, this development underscores the importance of strong security practices amid rising threats targeting digital asset storage.
