Trezor Suite functions as a companion application to hardware wallets, providing a clear interface for sending, receiving, and managing cryptocurrency. The Suite’s security model centers on isolating private keys on the physical device, enforcing local user authentication, and minimizing exposure to online threats.
Core Security Features
- Private Key Isolation: Private keys never leave the hardware device; transactions are signed offline and only signed payloads are transmitted.
- PIN and Passphrase: Multi-layered authentication with a device PIN plus optional passphrase reduces the risk of unauthorized access.
- Recovery Seed: Secure, human-readable backup of wallet state; store it offline and never in cloud storage or photos.
- Open-Source Transparency: Publicly auditable software enables community review and independent security validation.
- Transaction Verification: All transactions must be confirmed on the device screen, ensuring the host computer cannot silently alter amounts or addresses.
Operational Security: Use official downloads, verify checksums, enable firmware verification where available, and keep recovery seeds offline in a secure location.
Site-Level Security Guidance (for web operators)
To protect your website and users, enforce HTTPS, set strict HTTP headers (HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy), and deliver a server-enforced Content Security Policy. Avoid embedding external JavaScript without integrity checks (SRI).
