Detailed explanation & security notes
Many users expect a login form when they first open Trezor Suite. Instead, the security model is intentionally different: the hardware device is the authentication factor. Your PIN protects the device locally — it is entered on the device using a scrambled keypad shown in the host UI so that keyloggers on the host cannot learn the PIN. The optional passphrase acts like a 25th word that changes which wallet is derived from the seed. Use passphrases only if you understand the trade-offs; they provide strong additional protection but increase the complexity of backups.
To "log in" to your wallet from a new computer: plug in your Trezor, open the official site or Suite, and enter the PIN on the device when prompted. If the device was initialized with a passphrase, supply that passphrase as well. The host software will then display accounts and balances without ever exposing private keys — signing always happens on-device. This approach minimizes the attack surface: even if your computer is compromised, attackers cannot sign transactions without the physical device and the PIN/passphrase.
If you lose your device, recover your wallet on a new Trezor (or compatible wallet) using the recovery seed. Because the seed is the ultimate secret, store it securely offline. If you worry about theft or coercion, store part of your recovery strategy in a safe place or use multisig arrangements.
Final checklist
- Always use official trezor.io/start for downloads.
- Never enter your recovery seed into a computer or website.
- Use a PIN and consider a passphrase for extra security.
- Verify transaction details on the device before approving.
This guide should clarify what "Trezor login" means in practice: it’s not a username/password but a hardware-anchored unlock flow.
