Best practices for secure access

The Trezor model creates a distinct security paradigm compared to traditional web logins. Because private keys never leave the device, remote servers or websites cannot directly control your funds — they can only request the device to sign transactions. This means that "logging in" with Trezor is safer by design, provided you follow safe operational procedures.

Start by using official software: Trezor Suite (download at trezor.io/start) or audited third-party wallets that explicitly support Trezor. The device communicates with the application via a secure protocol; however, the host computer can be compromised. Always verify critical details (recipient address, amount, fees) on the Trezor display before approving a transaction. The on-device screen acts as your single source of truth.

PINs and passphrases are primary defenses for physical theft and plausibly deniable wallets. Choose a strong, nontrivial PIN and avoid patterns. If you enable a passphrase, treat it like an additional password that is never written down near your seed — losing it is equivalent to losing the funds it protects. For high-value holdings, consider using multisignature setups that spread custody across multiple devices or participants.

When connecting, prefer your own trusted machine. Avoid public computers and public Wi‑Fi when performing sensitive actions. Keep firmware updated via official channels; firmware updates can contain security fixes. Never enter your recovery seed into a website or provide it to support — Trezor support will never request your seed phrase. If any page asks for your recovery words, treat it as fraud.

Operationally, maintain multiple backups of recovery words stored in secure, geographically separated locations — paper, or better, a metal backup for durability. Test small transactions before sending large sums. For teams or families, consider clearly documented emergency procedures and custodial roles so funds remain accessible in an emergency without exposing secrets to unnecessary risk.

Finally, be wary of phishing. Malicious sites may mimic wallet UIs and try to trick you into connecting and revealing details. Always verify domain names and use bookmarks for official pages. If something feels off, disconnect the device and inspect the host environment before proceeding.

Recuerda: seguridad y hábito — regular, cautious behavior keeps your crypto safe for the long term.
