Before you begin — preparation checklist

Gather these items before starting:

  • Your Trezor device (Model One, Model T, or compatible edition).
  • A data-capable USB cable or adapter for your computer.
  • A secure, offline space to write your recovery seed (sturdy paper or a metal backup plate).
  • A computer with the latest OS updates and antivirus/malware protection.
  • Patience: do not rush through any prompts or skip verification steps.

Step 1 — Verify packaging & device

On arrival, inspect the packaging and device for tamper evidence. If seals are broken or the device shows signs of physical tampering, contact official support before using it. Trezor devices ship in tamper-evident packaging to help you detect interference.

Step 2 — Download official software

For the safest experience, use Trezor Suite (desktop) or official web tools from the Trezor domain. Do not download installers from third-party mirrors or follow links from untrusted emails. Use the links on this start page to reach official downloads and documentation.

Step 3 — Connect and initialize

1. Connect your Trezor device to your computer using the USB cable.

2. Launch Trezor Suite or visit the official start flow. The software will detect your device and prompt to initialize it.

3. Choose between Set up as new device or Recover device (if you already have a recovery seed). For most new users, select Set up as new.

Creating a PIN

During setup, you'll be prompted to set a device PIN. Choose a PIN that is not easily guessable. The PIN protects the device when it is physically connected — memorize it and avoid writing it down where it can be found with your recovery seed.

Generating and recording your recovery seed

Your device will generate a recovery seed — typically 12, 18, or 24 words depending on model and preference. Write these words down exactly and in order on the supplied recovery card or a secure medium. Do not photograph the seed or store it digitally (no screenshots, cloud notes, or photos).

Create multiple backups in geographically separated secure locations (e.g., a safe and a safety deposit box). Consider metal backup plates for fire and water resistance.

Step 4 — Verify seed and complete setup

After writing the seed, the device will ask you to confirm several words. This ensures you recorded the seed correctly. Complete the verification prompts on the device to finish setup.

Step 5 — Firmware updates

Check for firmware updates in Trezor Suite. Firmware updates add features and security fixes. Always update firmware using official tools and follow instructions precisely. Do not disconnect your device during an update. If an update is interrupted, follow official recovery steps — do not attempt ad-hoc fixes from unknown sources.

Advanced: Passphrase (optional)

Optionally, enable a passphrase for extra protection. A passphrase is an additional word (or string) combined with your recovery seed to create a distinct wallet. It dramatically increases security but must be remembered exactly. If lost, funds protected by a passphrase are irretrievable. If using passphrases, consider secure physical storage or memorization strategies and understand the complexity they introduce.

Step 6 — Add accounts and test

Once set up, open Trezor Suite or a supported wallet and create cryptocurrency accounts. Send a small test transaction when sending funds to a new address to confirm everything behaves as expected. Always verify the destination address and amount on your Trezor screen before confirming.

Recovery process

If your device is lost, stolen, or damaged, you can recover funds using your recovery seed. Purchase a new compatible device or use a secure, compatible recovery tool that supports your wallet standard, then select Recover device and enter your seed words in order. After recovery, set a new PIN and verify balances. Be cautious: never enter your seed into a website or an unverified tool.

Troubleshooting common issues

Device not recognized: Try a different USB cable and port, ensure Trezor Suite or Bridge is installed, and confirm OS drivers are up to date.

Device shows an error: Note the error text and consult official documentation. Many errors have step-by-step resolutions in the support center.

Firmware update problem: If a firmware update fails, follow the recovery guide in official documentation. Do not enter your seed into unknown recovery tools.

Security best practices

  • Never share your recovery seed or passphrase. No legitimate support agent will ever ask for them.
  • Keep backups of your seed in secure, separate locations.
  • Use only official software and verify download checksums when provided.
  • Avoid public or untrusted computers for initialization or recovery.
  • Consider physical hardening (tamper-evident bags, metal backups) for high-value holdings.

FAQ

Can I change the seed length?

Seed length options vary by model and firmware. Trezor Suite will present the recommended options during setup.

What if I forget my PIN?

Forgetting your PIN requires wiping the device and restoring from your recovery seed. This protects your funds from unauthorized access but emphasizes why secure seed backups are essential.
