Trézor.io/Start® | Starting Up Your Device

1. Before you begin

What you need

Your Trézor® device out of its sealed packaging (Model One, Model T, Safe 3/5 as applicable).
A computer (or supported mobile) and a reliable internet connection.
A pen and the included recovery backup card (or a dedicated metal backup) to write your wallet backup words.

Initial safety checks

Inspect packaging for tamper evidence. If anything looks suspicious, contact official support before continuing. Genuine setup starts at Trézor’s official start page where the Suite guides the process step by step.

Primary setup reference: Trézor's official start page provides the interactive setup flow and is the right place to start. See the links list at the end.

2. Step-by-step setup

Step 1 — Connect & open Trezor Suite

Plug your Trézor® into your computer using the supplied cable.
Open Trezor Suite (web or desktop) and follow the prompts to Set up my Trézor. The Suite will guide firmware installation if needed.

Step 2 — Install firmware

The device ships without firmware or may prompt an update. Install latest firmware through the Suite; follow on-screen instructions to allow device restart into bootloader and complete install.

Step 3 — Create your wallet backup

During initialization you’ll be shown a wallet backup (seed words). Write these words down in order and store them offline. Do not photograph or store them digitally.

Practical notes

Most wallets use 12 or 24 words—enter exactly what the device displays in order.
Consider using a metal backup (e.g., Trezor Keep Metal) for long-term durability.

3. Recovering a wallet

When to recover

Use recovery to restore funds on a new device after loss, damage, or factory reset. Select Recover wallet in Suite and carefully type each word in order.

Recovery tips

Confirm number-of-words matches your backup (12/24 or other supported lengths).
If your recovery fails, re-check spelling/order and try again in a private environment.

Security warning: Never share your backup words with anyone — Trezor (official) will never ask for them.

4. Firmware updates & maintenance

Why update firmware?

Firmware updates deliver security improvements, bug fixes and new features. Install updates via Trezor Suite when prompted; always ensure you have access to your wallet backup before major updates.

Troubleshooting

If update problems occur, consult official troubleshooting guidance — some issues require reinstalling Suite, using a different cable, or following the device bootloader instructions provided by Trezor support.

5. Everyday usage & best practices

Sending and receiving funds

Use Trezor Suite to create receiving addresses and to sign transactions. Always confirm the address on your device’s screen (trusted display) before sending funds.

PINs, Passphrases & Extra security

Set a device PIN — this protects against local physical access attempts.
Optionally use a passphrase (acts as a 25th word); treat it like a password — if forgotten, funds linked to that passphrase are irrecoverable.

Backup testing

Use the Suite’s “Check backup” feature occasionally to validate your written backup without fully restoring to a new device.

6. Common mistakes to avoid

Top pitfalls

Storing your recovery backup digitally (photos, cloud). Never do this.
Sharing your seed with anyone claiming to be support.
Buying used devices without ensuring firmware and provenance.

7. Advanced topics (brief)

Multi-share and advanced backups

Advanced backup schemes such as multi-share (SLIP-0039) exist for organizational use; consult official guides if you need multi-party recovery options.

Third-party apps & coin support

Trezor supports many cryptocurrencies, and some coins use third-party wallets. Always verify compatibility before moving funds.
