Quick overview
Trezor hardware devices isolate private keys on a secure element and require physical confirmation for sensitive actions. Logging in to your wallet means connecting the device, unlocking it with a PIN (and optional passphrase), and approving transactions on the device screen. This guide covers each step and highlights the habits that keep your funds safe.
Prepare the environment
Use a trusted computer for the initial login and for firmware updates. While Trezor is resilient to many host compromises, reducing risk is good practice: avoid public or shared machines when performing setup or large transfers. Ensure your browser and the official Trezor Suite or supported web wallet are up to date.
Connect your device
Plug your Trezor in using the supplied USB cable. The device boots into its home screen. Open Trezor Suite or the supported web wallet. If the site asks to pair, confirm you are on the official domain and accept the connection. The device will usually show a fingerprint or pairing prompt — verify it matches what the application displays.
Enter your PIN safely
The Trezor device uses a randomized keypad: your computer shows a numbered layout, but the numbers map differently on the device each time. Enter the PIN by clicking the positions on-screen while confirming the digits on your hardware display. This prevents keyloggers and malicious hosts from learning your PIN.
Optional: use a passphrase
Add a passphrase to create hidden wallets for additional privacy and security. When enabled, you enter the passphrase at login time; each distinct passphrase unlocks a different wallet. Treat passphrases as permanent secrets — if you forget one, you will lose access to that hidden wallet's funds.
On-device verification: your last line of defense
When preparing a transaction, the host prepares the data but the device displays the critical details: destination address, amount, and fees. Always verify these values on the device screen before approving. Malware on the host can change the web UI but cannot alter what the hardware displays — approving on-device ensures you sign the correct transaction.
Common login issues & fixes
If your computer doesn't detect the device, try a different USB cable or port. Rebooting the host or reinstalling Trezor Suite often resolves detection issues. If firmware updates fail, avoid forcing third-party fixes — reach out to official support and verify downloads.
- Device not powering: try another cable or check port debris
- Host can't see device: allow USB permissions, restart browser
- Repeated PIN failures: restore from seed on a new device if needed
Recovery and lost devices
If your Trezor is lost or irreparably damaged, you can restore your wallet on another compatible device using your recovery seed. Keep the seed offline, written exactly as provided, and stored in multiple secure locations. Never enter your seed into a website or digital file.
Security habits for daily use
Lock or disconnect your Trezor when not actively using it. Revoke permissions granted to web apps and regularly check your account activity. For large transfers, send a small test amount first. Consider using a dedicated machine for high-value operations and enable passphrase protection if you need plausible deniability.
