Step-by-step setup
1. Inspect device & packaging
Start by checking the box and the device for tamper evidence. Unopened packaging should look factory-sealed. If any seals are broken or the device looks modified, do not proceed — contact the vendor or the official Trezor support channel.
2. Connect to the computer or phone
Connect the device with the official cable. For mobile devices use an OTG adapter if needed. Use only trusted machines; avoid computers you don't control. The Trezor will show a welcome screen requesting you to visit trezor.io/start
.
3. Use the official website and verify URLs
Always navigate to the official onboarding address typed directly into your browser: trezor.io/start. Confirm the site certificate (click the padlock) and verify that the page is served over HTTPS. Beware of phishing pages and search-engine results that look similar.
4. Install recommended software
Follow the official instructions to install the Trezor Suite or use the recommended browser extension. When prompted, install device firmware only from the official source. Never install third-party firmware.
5. Initialize & create a new wallet
Choose "Create new wallet" on the device and in the suite. The device will generate a recovery seed (a series of words) privately inside the hardware. Write these words down carefully and in order — do not store the seed as a file or photo.
- Choose to create a fresh seed (recommended) rather than restoring from an unknown source.
- Consider optional passphrase protection for enhanced security — this acts as a 25th word and must be remembered.
6. Backups and storage
