Hardware wallet maker Trezor has increased the maximum length of optional wallet passphrases from 50 to 128 characters.  On Sunday, Trezor said the change is available in its Trezor Suite with updated device firmware. Older firmware still limits passphrases to 50 characters.  According to Trezor, a passphrase acts like an additional password that users set alongside their wallet’s recovery phrase. An attacker who obtains the recovery phrase would still need the correct passphrase to access funds in that wallet.

Chainflip in Trezor Suite is live via SwapKit. Trezor users can now swap native BTC, ETH and SOL cross-chain and confirm every swap on their device.

Sending coins to an exchange just to swap them and then withdrawing them again is a lot of work for one trade. Skip the exchange and trade directly in Trezor Suite. No more round trips through…

​A visual synthesis of the top emerging threats in this week's Cybersecurity Roundup: Exploring the physical supply chain risks with a Trezor Safe 5 hardware implant, the rapid accumulation of $1 million in fraudulent costs through LLMjacking, and the dramatic compression of the SAP exploit weaponization cycle to a mere 1 to 3 days. November 6, 2026 Three stories this week point to the same problem: attackers are getting to the money faster than defenders can respond.

Trezor Implant Threat Emerges Security researchers have identified a sophisticated implant that targets the firmware of Trezor hardware wallets. The malicious code is designed to intercept seed phrases during the device initialization process, allowing attackers to extract private keys without triggering user alerts.
