1Hardware wallet maker Trezor has increased the maximum length of optional wallet passphrases from 50 to 128 characters.
2The new feature is available in Trezor Suite with updated device firmware, while older firmware keeps the 50-character limit.
3Trezor noted that passphrases act as an additional password alongside a recovery phrase to protect funds.
4The update was partly inspired by July Coldcard attacks where strong passphrases helped protect users whose recovery info was compromised.
5Trezor also recently advised customers who bought devices from a specific former reseller since March to move their funds due to a potential hardware compromise.
Key takeaway
Trezor is improving its security offerings by allowing longer passphrases following past industry incidents, while separately warning some customers about potential supply chain tampering.
