Why initialize your Trezor the official way?
Initializing a Trezor hardware wallet is the first and most important step in keeping your crypto safe. The process creates a secure root of trust and a seed phrase that only you should control. Use the official start page and the steps below to make sure the device is genuine, firmware is official, and the seed is generated in the device — not on a computer or phone.

Pre-setup checklist
Essentials
- Your brand-new Trezor device (Model T or Model One).
- A clean, trusted computer or mobile device and official cable.
- Access to the official Trezor start page:
trezor.io/start. - Blank recovery card or secure notebook and a pen (do not store seed digitally).
Security reminders
Do not connect your Trezor to an unknown or public computer. Always verify firmware authenticity using the official start flow. Never share your recovery seed — not with support, not with friends.
Step-by-step: Initialize your device™
Step 1 — Verify device packaging
Inspect the box and tamper seals. A genuine device will show factory seals intact. If something looks damaged or suspicious, contact official support before proceeding.
Step 2 — Visit the Official Start page
Open a browser on a trusted machine and go to trezor.io/start. The official page walks you through downloading the Trezor Suite (desktop or web) and verifying firmware signatures.
Step 3 — Connect and verify device
Connect your Trezor with the official cable. The device screen will show a unique fingerprint and prompts. The start flow verifies the device by checking firmware authenticity and prompting you to confirm the expected fingerprint on the Trezor's display.
Step 4 — Create a new wallet
In the official Suite or start flow, choose Create new. The device will generate a recovery seed (the seed generation happens on the device only). Follow the on-screen instructions to write down every word in order.
About the recovery seed (h4)
The recovery seed (usually 12, 18, or 24 words) is the only backup of your wallet. Store it offline, preferably written on multiple copies and kept in separate secure locations. You can also consider metal backup plates for fire/water protection.
Step 5 — PIN and label
Set a secure PIN on the device. This adds an extra layer if someone obtains your Trezor physically. Add a label (e.g., "Cold Wallet #1") to help you distinguish multiple devices.
Security best practices (h2)
Never type your seed into a computer
The seed is meant to be written by hand. Typing it into a machine exposes it to keyloggers and malware. If you must use digital backups, prefer encrypted, air-gapped solutions and use them only if you fully understand the risk.
Keep firmware updated
Official firmware updates patch security issues and add features. Always update only through the official start flow: trezor.io/firmware.
Advanced: Passphrase (h4)
Trezor supports an optional passphrase that acts as a 25th seed word. Use this only if you understand how it works — a lost passphrase cannot be recovered. Use it to create hidden wallets or add an extra layer of deniability.
Troubleshooting & common questions (h2)
My device isn't recognized
Try a different USB port and cable. Ensure your OS has the latest updates and that you downloaded Suite from trezor.io/suite. If problems persist, check official support resources.
Lost or damaged recovery seed
If you lose the seed and still have access to your Trezor and its PIN, immediately move assets to a new wallet and create a fresh seed backup. If you lose both seed and device, funds are irrecoverable.
What if I suspect compromise?
If you suspect your device or seed was exposed, move funds to a new wallet initialized on a brand-new device as soon as possible. Contact official support for guidance.
Helpful official resources (h5)
Designing your backup strategy
A resilient backup plan includes multiple physical copies stored in geographically separate secure locations and, when appropriate, hardened backups like stainless steel plates. Consider legal and inheritance planning: document access procedures for trusted beneficiaries without revealing the seed or passphrase.
On sharing: be paranoid by default
No legit service will ask for your recovery seed or private keys. Treat anyone requesting them as malicious. If someone offers to "help" by taking your seed, refuse and report.
Final checklist before first transaction
- Device verified on official start page.
- Firmware authenticated and up to date.
- PIN set and tested (remember your PIN — too many wrong attempts may wipe the device).
- Recovery seed written, double-checked, and stored offline.
- Optional passphrase understood and recorded (if used).
Closing notes
Initializing your Trezor via the official start page creates a strong foundation for secure crypto custody. Follow the steps above, use the official links and resources included, and keep safety first: the fewer places your seed touches a digital screen, the safer your funds will be.
