Trezor.io/Start — Secure Crypto Wallet Setup Guide
Official flow Use this friendly guide to walk through the essentials you’ll encounter at trezor.io/start: unboxing, firmware, creating a wallet, backing up your recovery seed, and sending your first transaction with Trezor Suite. The steps below are written to mirror the official process while staying device-agnostic for Model One and Model T.
Tip: Bookmark the URL and type it in manually. Avoid look-alike sites. Your recovery seed never goes into any website or computer—only into your Trezor device.
Open your browser and go to trezor.io/start. Download Trezor Suite for your operating system and install it. Suite is the companion app that manages devices, accounts, addresses, fees, and security controls. Prefer the desktop app over a browser extension for a smaller attack surface.
You can verify the app’s signature from official sources if you practice strict security hygiene.
New devices often ship without the final firmware. Suite will prompt you to install or update. Confirm on the device. Do not disconnect during the process.
Your device will display a 12/20/24-word recovery seed. Write every word, in order, on the included card (or a metal backup for durability). This seed is the only way to recover funds if your device is lost or damaged.
In Suite, add accounts for the coins you plan to hold (e.g., Bitcoin, Ethereum). Each account has its own receive addresses derived from your seed.
Suite will display status and a transaction ID you can view on a block explorer.
Only update firmware and download Suite from trezor.io. Never share your seed with “support agents.”
Keep your device and backup separate. Consider enabling passphrase for plausible deniability.
Lock your computer, use unique passwords, and keep OS and Suite updated. Verify addresses on the device, every time.
What if I lose my device? Buy a new Trezor and select Recover wallet, entering your seed on the device. Funds are on the blockchain, not the device.
Can I use multiple computers? Yes. Your keys stay on the device; Suite is just an interface.
Is a passphrase required? No, but it meaningfully increases security if you can memorize it reliably.
