How to Set Up a New Trezor Wallet for the First Time Step by Step
You have a new Trezor in hand. The setup is straightforward, but small mistakes can cost you everything. This guide walks through each step, model by model.
Step 1: Verify the packaging and device
Before plugging anything in, inspect the box. The seal should be intact, with no tears or re-gluing. Trezor packages use tamper-evident tape. If the seal is broken or looks suspicious, do not proceed. Contact the seller or Trezor support directly.
Open the box. Inside you should find: - The Trezor device (Model One or a Safe model). - A USB cable. - A seed card (blank, pre-printed with numbered lines). - Lanyard and stickers (varies by model).
The device itself should show no scratches, dust under the screen, or loose buttons. The screen on Safe models has a protective film. The Model One has a small OLED display with no film.
Step 2: Download Trezor Suite from the official site
Go to trezor.io/start. Download Trezor Suite from there only. Bookmark the URL. Do not search for "Trezor Suite" and click the first link. Phishing sites clone the real page.
For Model One, you also need Trezor Bridge - the software that lets your browser talk to the device. Safe models work directly with Trezor Suite (desktop app) or via WebUSB in supported browsers. The desktop app is the safer choice.
Install Trezor Suite. Launch it.
Step 3: Connect the device
Plug in the Trezor using the included cable. Do not use a hub or extension cord. Plug directly into your computer's USB port.
The device screen lights up. Trezor Suite detects it and asks if you want to initialize a new wallet. Click "Set up as new device."
Step 4: Install or verify firmware
Trezor Suite checks the firmware. If the device is new from the factory, it may need an update. Follow the on-screen prompts. The device will ask you to confirm the firmware install by pressing a button (Model One) or tapping the screen (Safe models).
The update takes a minute. Do not unplug the device during this process.
After update, the device restarts. Verify the firmware hash on the screen matches what Trezor Suite shows. This confirms the firmware is genuine.
Step 5: Generate and back up the seed phrase
The device generates a 12-word (Model One) or 20-word (Safe 3 and Safe 5) seed phrase. This is your wallet. Lose it, lose your funds. Share it, lose your funds.
The seed appears on the Trezor screen. Write each word on the provided card in the exact order shown. Use the numbered lines. Write clearly - a scribbled word you cannot read later is as bad as a lost word.
Do not type the seed on your computer. Do not take a photo of it. Do not store it in a cloud service. The device never sends the seed over USB. Keeping it off any internet-connected device is the only defense.
Trezor Suite will ask you to confirm the backup - it shows a word and you select its position in the sequence. This verifies you wrote it down correctly.
Model One vs Safe models: On Model One, the seed appears on the tiny screen. Verified words are selected using the two buttons. On Safe models, the larger color screen shows the seed one word at a time, and you confirm by tapping the screen.
Step 6: Set a PIN
The device asks for a PIN. Choose one that is 4-9 digits (Safe models allow longer PINs). This PIN protects your device from physical access. Without it, someone who steals your Trezor cannot access your funds.
Enter the PIN using the scrambled keypad on the device screen. Never enter your PIN on your computer. That defeats the purpose.
Write down the PIN somewhere separate from your seed phrase. If you lose both, you are locked out.
Step 7: Confirm the backup with a dry-run check
After setup, Trezor Suite offers a "dry-run" recovery check. Do this now. It simulates recovering your wallet using the seed you wrote down. This proves your backup is accurate before any funds go on the device.
To run it: go to Settings > Device > Check seed recovery. The device walks you through entering your seed words. It does not change anything - it only verifies the backup matches.
If the check fails, your seed is wrong. Stop. Find the error or start over with a fresh device. Never put funds on a wallet with a bad backup.
Step 8: Send a test transaction
This is the step most people skip. Do not skip it.
Send a tiny amount - literally a few cents worth of bitcoin or the coin you plan to use - from an exchange or another wallet to your new Trezor address. Confirm the transaction on the device screen. Wait for the network to confirm (one confirmation is enough for a test).
Then send that tiny amount back out of the Trezor. This proves three things: you can receive, you can send, and your backup would work if needed.
Only after this test passes should you move significant funds.
Model-specific notes
Trezor Model One: Cheaper, smaller screen, two-button navigation. Requires Trezor Bridge. No USB-C (uses micro-USB). Seed is 12 words.
Trezor Safe 3 and Safe 5: Color touchscreens, USB-C, no Bridge needed with desktop app. Seed is 20 words. Safe 5 includes a microSD slot for encrypted storage backup (optional, not required). Both support longer PINs and passphrase directly on device.
One hard rule
Never enter your seed phrase into any computer, phone, or website. Not for "verification." Not for "recovery." Not for "customer support." Trezor will never ask for it. Anyone who does is stealing from you.
