How to Set Up a Hardware Wallet in 2026: Step-by-Step Guide
This guide covers the complete setup process for the four leading hardware wallets in 2026: Trezor Safe 7, Ledger Flex, Tangem, and OneKey Pro. Each section covers device verification, initial setup, seed phrase backup (or card-based backup for Tangem), PIN configuration, and a pre-transfer security checklist.

Buy only from official sources. Hardware wallet supply chain attacks are real. Buy directly from the manufacturer's official website or an authorised reseller. Never buy a used hardware wallet. Links in this guide go to official manufacturer sites.
Never enter your seed phrase on a computer or phone. No legitimate hardware wallet manufacturer will ever ask you to type your seed phrase into a website, app, or support chat. Any request to do this is a scam.
Before You Set Up: 5 Things to Check First
Box seal intact?
Check that the tamper-evident seal on the box is unbroken before opening. If it's broken, contact the manufacturer before proceeding.
No pre-written seed?
A legitimate device will NEVER come with a seed phrase written down inside the box. If yours does, do not use it — it's compromised.
Firmware update on first boot?
Most devices will prompt you to update firmware during first setup. Do it — this is legitimate and important.
Download apps from official sites only
Trezor Suite: trezor.io/start · Ledger Live: ledger.com/ledger-live · Tangem App: app stores from tangem.com · OneKey App: onekey.so
Prepare your seed backup materials
Have paper (or a metal backup plate) ready before starting. Never type your seed into any digital device.
Trezor Safe 7 setup is done entirely through Trezor Suite, the desktop app. The device's color touchscreen guides you through every step with on-screen confirmations.
- Download Trezor Suite from
trezor.io/start. Verify the download signature if you're security-conscious (instructions on the Trezor website).
- Connect your Trezor via USB-C and follow the Suite prompt to install firmware. The device will reboot after the update.
- Select "Create new wallet" in Trezor Suite. The device will generate entropy on-device and display your seed words.
- Write down all 12 or 24 seed words on paper, in order, as shown on the device screen. Triple-check spelling. Do not photograph them. Do not type them anywhere.
- Verify your seed — Trezor will ask you to confirm specific words from your seed on the device screen. This ensures your written copy is correct.
- Set your PIN on the device's touchscreen. Use 6+ digits. The PIN grid on the device is shuffled each time so a camera recording your computer screen can't reveal it.
- (Optional but recommended) Enable BIP39 passphrase in Trezor Suite settings. This creates a separate "25th word" — even if someone steals your seed phrase, they cannot access your funds without this passphrase. Store it separately from the seed.
- Test with a small amount — send a small amount to your new receiving address, confirm it arrives in Trezor Suite, then test sending it back before moving significant funds.

Ledger Flex setup uses Ledger Live, available for desktop or mobile (via Bluetooth). The E-Ink screen is crisp and readable even in bright light.
- Download Ledger Live from
ledger.com/ledger-live — not from a third-party source. Verify the authenticity badge in Ledger Live on first launch.
- Connect your Ledger Flex via USB-C (or Bluetooth to mobile) and follow the Ledger Live setup prompt.
- Update to the latest firmware if prompted. Genuine Ledger firmware updates are signed and verified automatically.
- Select "Set up as new device" — never "restore from recovery phrase" on a device you haven't wiped yourself.
- Write down your 24-word recovery phrase shown on the device's E-Ink screen. Ledger provides a recovery sheet in the box. Do not type it anywhere digital.
- Verify your recovery phrase — Ledger will ask you to confirm several words on the device screen.
- Set your PIN on the device's touchscreen. Use 6–8 digits. Ledger auto-wipes after 3 incorrect PIN attempts.
- Disable Ledger Recover — go to Settings on the device and confirm it is off. You do not need to enable it.
- Install coin apps via Ledger Live — you install lightweight apps for each coin type (Bitcoin, Ethereum, etc.) from the Ledger Live app catalogue.
- Test with a small transfer before moving significant funds.

Tangem is the easiest of the four to set up. Everything is done in the Tangem mobile app — no computer required. You receive 2 or 3 cards; each card becomes a backup for the others.
- Install the Tangem App on your iPhone or Android phone from the official link at
tangem.com (or use the install link below).
- Tap your first card to the back of your phone (NFC). The app will detect the card and start the setup wizard.
- Create a new wallet — the app generates private keys on the card's chip. Keys are created inside the chip and never leave it. You will not be shown a seed phrase at this stage (unless you choose to enable it).
- Set an access code (optional but recommended) — a PIN or passcode that protects the card from being used if physically stolen.
- Link your backup card(s) — tap your second (and third if available) card when prompted to create backup links. This is Tangem's recovery mechanism. Keep backup cards in separate secure locations.
- (Optional) Enable seed phrase backup — in the app settings, you can generate and back up a standard seed phrase if you prefer traditional recovery alongside card-based recovery. Most users skip this and rely on the card backup.
- Test with a small amount before moving significant funds — receive a small transfer and confirm it shows in the app.

OneKey Pro setup uses the OneKey App (desktop or mobile). Its QR air-gap mode lets you set up and use the device without any cable — transactions are transmitted via QR code.
- Download OneKey App from
onekey.so. The app is available for macOS, Windows, Linux, iOS, and Android.
- Power on the OneKey Pro and follow the on-screen setup prompt.
- Update firmware if prompted — OneKey firmware updates are signed and open-source on GitHub.
- Select "Create new wallet". The device generates your seed phrase internally and displays it on its color touchscreen.
- Write down your 12 or 24 seed words from the device screen. Do not type them anywhere.
- Verify your seed on the device — the device will test specific words from your phrase.
- Set a strong PIN on the device's touchscreen (6–8 digits recommended).
- (Optional) Enable QR air-gap mode — in device settings, you can switch to air-gap mode where all signing is done via QR code with no USB or Bluetooth connection. This is the recommended mode for high-value treasury use.
- Test with a small amount before moving significant funds.

Post-Setup Security Checklist
After setup, run through this checklist before moving significant funds to your new wallet.
- Seed phrase (or backup card) stored in a physically secure location — ideally fireproof and waterproof
- Seed phrase NOT stored in any digital format (no photos, no cloud docs, no password manager)
- Passphrase (25th word) set for seed-phrase wallets holding significant value — stored separately from seed
- PIN set to 6+ digits, not a memorable date or sequence
- Test transaction sent and received successfully before moving large amounts
- Firmware up to date
- Receiving address verified on device screen before sending to it (not just relying on clipboard)
- Ledger Recover confirmed off (Ledger users)
- Recovery tested at least once: restore using seed phrase (or backup card for Tangem) to confirm it works
Common Setup Mistakes to Avoid
Photographing your seed phrase
Cloud photo services (iCloud, Google Photos) auto-sync images. A photo of your seed phrase stored in cloud storage is effectively stored on a server. Write it on paper — or better, stamp it into a metal backup plate.
Skipping the seed phrase verification step
Most wallets ask you to confirm several words from your seed phrase on the device. Some users skip this by clicking through quickly. If you wrote even one word incorrectly, you will lose all funds if you ever need to recover. Do the verification step properly.
Using the wallet before testing recovery
Test your recovery before trusting significant funds to any wallet. Find a quiet moment, follow the "restore from seed" flow on a second device or after wiping and restoring the original. Confirm it works. Then move real funds.
Entering your seed phrase online
If any website, app, or "support agent" asks you to type your seed phrase, close the window immediately. This is always a scam. Legitimate recovery from a hardware wallet seed phrase happens on the hardware device itself, not in a browser.

Frequently Asked Questions
Can I set up a hardware wallet without a computer?
Tangem can be fully set up using only your smartphone. Trezor, Ledger, and OneKey all require a computer (or Bluetooth phone for Ledger) for the companion app and initial firmware verification.
What happens if I lose my hardware wallet?
For seed-phrase wallets: buy a replacement device and restore using your seed phrase — all funds will reappear. For Tangem: use your backup card. Your PIN protects the original device from being used by whoever finds it.
Should I add a passphrase (25th word)?
Yes, for significant holdings. A BIP39 passphrase means that even if someone has your seed phrase, they cannot access your funds without the passphrase. Store the passphrase separately from the seed words — in a different physical location.
