Device-Based Authentication Built for Maximum Protection
Trezor does not use traditional web logins. There are no usernames, passwords, or online accounts. Access to funds is controlled through physical device authentication, ensuring private keys never leave the hardware wallet.
The wallet connects via USB and establishes an encrypted communication channel with the Trezor interface.
Users enter a PIN. The keypad layout is displayed only on the device, protecting against keyloggers and screen capture attacks.
An additional passphrase can create hidden wallets, adding a second layer of protection even if the device is physically stolen.
Transactions and sensitive actions must be confirmed directly on the device, preventing malware from approving actions silently.
Users must protect their recovery seed and device PIN. Trezor cannot reset passphrases or restore lost seeds — ownership remains fully in the hands of the user.
Trezor hardware authentication replaces risky online logins with cryptographic proof of ownership and physical verification, delivering true self-custody security.
