Trezor.io/Start® — Start Up Your Device®
Quick orientation
Congratulations on your new Trezor® device. This guide walks you through everything needed to get started: unboxing, installing software, initializing the device, creating a secure backup, updating firmware, and basic troubleshooting. Follow these steps carefully — your security depends on them.
Set up your Trezor® — recommended flow
Open the package and check for tamper-evident seals. If the device or packaging looks tampered with, contact support — do not use it.
Go to trezor.io/start and follow the official link to download Trezor Suite (desktop) or use the recommended web app. Always verify the domain and certificate before downloading.
Plug the Trezor into your computer using the supplied cable. Some models support USB-C or USB-A adapters; use the cable included with the product where possible.
Follow on-screen instructions to create a new wallet. Choose whether to create a new backup (recommended) or recover from an existing seed phrase.
Write the displayed recovery words on the supplied recovery card or another physical medium. Store this backup securely and separately from your device.
Choose a PIN you can remember but is hard to guess. The PIN adds protection even if your device is stolen. Trezor will never ask for your PIN over the internet.
If prompted, update the device firmware through the official app. Firmware updates include security improvements — verify updates come from the official source before installing.
Before moving large funds, send a small test transaction to and from your new wallet to confirm everything works as expected.
Create a new wallet vs recover an existing one
When you initialize, you have two options:
- Create a new wallet: Trezor generates a new recovery phrase (usually 12, 18, or 24 words depending on model). Write it down immediately and store it safely.
- Recover wallet: If you already have a recovery phrase, choose the recovery option and enter your words carefully to restore access to your accounts.
If using passphrase (optional advanced feature), be aware it acts like a 25th word — losing it means losing access to that derived wallet. Use passphrase only if you understand implications.
Keeping your device up to date
Firmware updates are signed and distributed through official channels. The app will prompt you when an update is available. Always verify:
- Update prompts appear in the official Trezor Suite or at
trezor.io. - Do not install firmware from unknown sources or links sent by untrusted parties.
In rare cases, firmware updates may require reinstalling or reinitializing the device — follow on-screen instructions and keep your recovery phrase handy (do not share it).
Common issues & fixes
- Device not recognized: try a different USB cable/port, or a different computer. Avoid USB hubs for initial setup.
- App won't load: clear browser cache, restart the app, or use the desktop Suite.
- Forgot PIN: unlocking attempts are limited — if you forget your PIN, the only safe recovery is to wipe and restore using your recovery phrase.
- Lost recovery: without your recovery phrase, funds cannot be recovered. Treat the recovery phrase as your last-resort backup.
If issues persist, consult the official support center or community forums for additional help.
Frequently asked questions
Q: Can someone steal my crypto if they get my Trezor?
A: Not if you use a PIN and keep your recovery phrase private. The PIN prevents immediate access; the recovery phrase is needed to move funds elsewhere.
Q: Is Trezor compatible with my coins?
A: Trezor supports many major coins natively and additional coins via community or third-party integrations. Check the official coin support list for specifics.
Q: Should I keep my firmware updated?
A: Yes — updates patch vulnerabilities and add features. Always use official update channels.
For power users & developers
Developers can integrate with Trezor using official libraries and SDKs. Advanced users may use the command-line tools for scripting or hardware-backed signing in automation — but never expose your recovery phrase to scripts.
// Example: connect to a Trezor device using a community SDK (pseudocode)
const device = await Trezor.connect();
const accounts = await device.getAccounts({ coin: 'btc' });Always run developer tools on trusted machines and never embed recovery data into code or CI pipelines.
