1. Install and run Trezor Suite
If you don’t have installed yet go to trezor.io/start and click Download for desktop.
Once the installation is finished, open Trezor Suite.
2. Connect and verify your Trezor
When Trezor Suite opens, you’ll see “Connect & unlock your Trezor.”

Plug in your Trezor Safe 5 using the USB-C cable.
After connection, Suite will display the Device security check.

If anything looks unusual, see Authenticate your Trezor Safe 3 for guidance on verifying your device.
3. Install firmware
Your Trezor ships without for security.
Trezor Suite will guide you to install the latest version of the firmware.

You can choose between Standard or Bitcoin-only firmware.
Click Install firmware and wait for the installation to complete.
Your Trezor will restart automatically.
4. Authenticate your device and learn the basics
After firmware installation, Trezor Suite will perform a Secure Element authenticity check.
This cryptographic check confirms your Trezor Safe 5 was genuinely made by Trezor and hasn’t been altered.
Click Start and follow the steps on the Trezor device to complete the check.

After the authenticity check, your device will offer a short tutorial "Know your Trezor."

Follow the tutorial on your Trezor device, or click Skip. Once completed, click on Continue:
5. Create your wallet and make a backup
Trezor Suite now guides you through creating your wallet and your wallet backup.

Click Create a new wallet if this is your first setup, or Recover if you’re restoring one from an existing backup.
After selecting Create a new wallet, you’ll see a screen where you can choose your wallet backup type.

About your backup type: Your Trezor Safe 3's default backup type depends on when your device was made:
- 2023 devices with recovery seed cards: default is 12 words
- 2024+ devices with wallet backup cards: default is 20 words
Both 12-word and 20-word backups are secure. However, 20-word backups allow you to upgrade to multi-share later, while 12-word backups remain single-share only. If your device defaults to 12 words, you can change it to 20 words by clicking the Wallet backup type dropdown. For a detailed explanation of backup standards and number of words, see Understanding Trezor wallet backups.
Click Create wallet. Your Trezor will ask you to agree to the Terms of Use. Press the right button to create your wallet.

Once your wallet is created, click Continue to wallet backup.
Trezor Suite will first show you backup instructions. Read them carefully and confirm you understand by checking the boxes.

Once you have reviewed those messages, click Create wallet backup.
Your Trezor device will instruct you to write down the words and keep them private.
Write down your wallet backup words:
Your Trezor Safe 7 will display your wallet backup words, one by one. These words form your wallet backup and are the key to restoring access to your wallet.
Your backup is the only way to recover your wallet. Write each word in the exact order on one of the provided wallet backup/recovery seed cards. If the words are lost or written incorrectly, your wallet cannot be recovered.
Navigate using the up and down arrows on the device. You can go backwards to review your words order and spelling. When you are finished, tap Continue.
Your Trezor will then ask you to select specific words from your backup to verify you've written them down correctly.

Never enter your backup anywhere other than directly on your Trezor device. Fake apps and websites may try to trick you into typing your words. If you do, your funds can be stolen. Keep your backup written on paper or metal and stored safely offline.
6. Set a PIN
After your wallet backup is created, Trezor Suite will ask you to set a PIN.

Your PIN protects your device from unauthorized access.
Click Set PIN and follow the on-screen instructions.
Your Trezor Safe 3 will prompt you to enter the PIN using the device's buttons.
You'll enter your PIN on your Trezor Safe 3 using the device buttons. Use the left and right buttons to navigate to each digit. Press both buttons to select a digit. The cursor position changes each time for security.
- Use a PIN of at least 4 digits. You can use up to 50 digits.
- Avoid simple sequences (for example, ‘12345’) and numbers that are personally meaningful (birthdays, etc.).
- You can change the PIN later in Settings → Device.
- The device allows 16 incorrect PIN attempts.
- After 16 incorrect PIN attempts, the wallet will be erased from the Trezor device. You can only restore your wallet with the wallet backup.
To learn more about creating and managing your PIN, see PIN protection on Trezor devices.
You can use the space provided on your wallet backup card if you want to write down your PIN. Always keep your wallet backup private and offline.
