Trezor Hardware® LoginⓀ

Make sure you have:

• A genuine Trezor Model One or Trezor Model T purchased from the official store or an authorized reseller.
• The USB cable included in the box and a computer running Windows, macOS, or Linux.
• Access to Trezor Suite (download from suite.trezor.io) and, if needed, Trezor Bridge (trezor.io/bridge).
• A secure place to write your recovery seed — never store it digitally.

Inspect packaging and tamper seals. If anything looks altered, do not use the device; contact official support. Genuine devices include seed cards, a USB cable, and documentation.

Always confirm you bought from trezor.io or an approved reseller to avoid counterfeit units.

1. Go to trezor.io/start and choose your model.
2. Connect your Trezor to the computer using the cable. Device screen will power on and show welcome prompts.
3. Follow the on-screen instructions in Trezor Suite. If prompted, install or update firmware — always accept firmware only from the official app or site.

Important: Do not accept firmware files from unknown sources. Firmware updates are verified by the device and Suite — this protects against modified firmware.

When initializing, Trezor will generate a recovery seed (12/18/24 words). Write the words on the supplied recovery cards, store them offline in at least two secure locations (e.g., safe deposit box, fireproof safe), and never photograph or save them digitally.

Use a passphrase (optional) only if you understand how it works — it creates additional hidden wallets and increases security but also increases recovery complexity.

Logging in with Trezor is a physical, stepwise operation:

1. Open Trezor Suite or the supported web/DApp you want to use.
2. Click Connect Trezor (or “Login with Trezor”).
3. Confirm the request on your device screen by pressing the device buttons (Model One) or tapping (Model T).
4. Enter your PIN on the device when requested — the layout is randomized to prevent keyloggers from capturing PINs.
5. After device confirmation, the app signs the login challenge and grants access — your keys remain on the device at all times.

Why this is safe: the challenge-response login means the site never receives your private key. Approval happens on the Trezor hardware, so malware on your computer cannot authorize logins or transactions.

• Device not detected: Try a different USB port or cable. Ensure Bridge (if required) is installed.
• Browser problem: Use Chrome or Edge for best WebUSB compatibility, or use the desktop Suite.
• PIN or passphrase forgotten: If PIN is lost you must use your recovery seed to restore on a new device.
• Firmware update failed: Restart the device and computer, reinstall Suite/Bridge, then retry. If stuck, contact official support.

• Never share your recovery seed with anyone — not support, not friends. No legitimate support will ask for it.
• Keep your device firmware up to date through Trezor Suite only.
• Use a strong PIN and consider a passphrase for additional privacy.
• Store seed backups offline (metal backup is recommended for long-term resilience).
• Use Tor mode in Trezor Suite if you want extra network privacy.

Trezor works with many wallets and Web3 applications. When connecting to third-party services (MetaMask, MyEtherWallet, etc.), always confirm every transaction on your device screen. For DApps and DeFi, prefer read-only actions in your browser and sign only when you intentionally approve operations on the device.
