Security best practices

Keep your recovery seed offline and private. Never enter the seed into a computer or phone. Use metal backup plates if you want a fire- and water-resistant backup. Consider splitting the seed across geographically separate secure locations if you need redundant protection.

Only interact with the official site at trezor.io. Phishing attacks impersonating wallet interfaces are common — verify the URL and the TLS padlock in your browser. Use hardware verification: always confirm transactions on the Trezor screen before approving them.

Using your Trezor

Once set up, you can send and receive cryptocurrency through the Trezor web app or compatible third-party wallets that support Trezor. When receiving funds, always confirm the address on the device. When sending, verify the transaction details on the device display, including the amount, destination address, and network fees.

Advanced users can enable passphrase protection for an additional layer of security. A passphrase acts like a 25th seed word and can create hidden wallets. Be careful: passphrases are not recoverable—if you forget it, the hidden wallet and its funds are lost.

Troubleshooting

If your device is not recognized, try a different USB cable or port. Some USB hubs or charging-only cables do not provide data connections. Reboot your computer and reinstall Trezor Bridge if necessary. Consult the troubleshooting section on the official start page for device-specific guidance.

If you suspect compromise or loss of your device, use your recovery seed on a new Trezor device or supported compatible wallet to regain access to your funds. Because your assets are controlled by the seed, you can recover them safely so long as the seed is secure.

Frequently asked questions

What happens if I lose my Trezor?

Your funds are not stored on the Trezor device — they live on the blockchain. With your recovery seed you can restore access on a replacement device. If you lose both device and seed, your funds are unrecoverable.

Can I update firmware later?

Yes. Firmware updates improve security and compatibility. Trezor will notify you of updates through the official app. Always install updates only from the official website.

Is Trezor open source?

Yes. Trezor’s firmware and hardware designs are open source, enabling independent review and community trust. Open-source design helps reduce the risk of hidden vulnerabilities.

Supported coins and integrations

Trezor supports many cryptocurrencies including Bitcoin, Ethereum, Litecoin, and numerous ERC-20 tokens. Check the compatibility list on the official site before managing a specific token.

Advanced features

Features such as multisignature setups are available for shared control over funds, and developers can integrate Trezor using official libraries and APIs.

Recovery drill

Practice restoring your wallet using only the recovery seed on a separate trusted device. This confirms your backup is correct without risking your main setup.

Privacy considerations

Use new receiving addresses for each transaction and learn about privacy tools if you need additional anonymity. Always consider legal implications in your jurisdiction.

Verify authenticity

Always verify firmware signatures during updates. The official setup flow checks signatures automatically, and the device display shows verification prompts. Do not accept firmware or prompts that appear suspicious.

More FAQs

Can I use multiple accounts?

Yes — Trezor allows multiple accounts and multiple cryptocurrency accounts within the same device. This helps separate holdings and manage funds for different purposes.
