Quick, secure steps and best practices to authenticate with your Trezor device and Trezor Suite without exposing keys or backups.
Signing into a Trezor-backed wallet is not like typical username/password sign-in. Your Trezor device holds the private keys and authorizes actions (PIN, passphrase, or on-device confirmation). The host app (Trezor Suite or a compatible wallet) only requests signatures — the Trezor device performs them securely on its screen.
Always download Trezor Suite or official integrations directly from Trezor’s official site. Avoid third-party or clone downloads that can intercept or spoof wallet communication.
Check your device for tamper evidence and confirm the device shows the genuine welcome and firmware prompts during setup. If anything looks unusual, stop and contact official support.
Use a personal computer you control. Ensure OS and browser are up to date and free of malware. Prefer a clean browser profile dedicated to crypto if possible.
Open the official Trezor Suite app (desktop or web) to manage accounts and sign transactions. The Suite will guide firmware installs and device authentication prompts.
Never enter your PIN on the computer. The device displays a randomized keypad — press corresponding positions on the computer only; the mapping prevents keyloggers from learning the PIN.
Always read the transaction or action details on the device display and confirm only what you recognize — addresses, amounts, and destination chains must match what you expect.
Use a passphrase to create a hidden wallet if you need extra obfuscation. Treat it like a password — losing it may permanently deny access, so store carefully offline.
Install official firmware updates via Trezor Suite when prompted. Firmware updates fix security issues and improve device behavior.
Keep your recovery backup (seed) offline and physically safe. Do not store seeds digitally or photograph them. If you use advanced backup formats, understand compatibility before relying on them.
If the device fails firmware update, or you suspect tampering, consult official troubleshooting guides and support channels before continuing. For lost devices, a correctly stored seed can restore funds to a new device or compatible wallet.
