In-depth: How Trezor Suite protects your assets
Trezor Suite is built around the principle of keeping secrets off the internet. Your private keys are generated and stored inside the secure elements of your hardware device. The Suite acts as a remote interface that requests signatures from the device — it never transmits keys. This separation means that even if your computer is compromised, attackers cannot extract keys or sign transactions without physical access to the Trezor and the PIN.
When restoring a wallet, the recovery seed is used to recreate private keys. Treat this seed as the ultimate backup — keep it offline, duplicated in secure locations, and consider using metal backups to protect against environmental risks. Trezor Suite’s open-source code and community audits provide additional assurance about the integrity of the software.
