Begin Secure Initialization at trezor.io/start

Essential Onboarding via trezor.io/start

When configuring a brand-new Model One, Safe 3, or Model T, opening trezor.io/start in an updated browser represents the single most important first step. This authorized landing environment ensures you download genuine Trezor Suite desktop software while steering clear of deceptive phishing domains, copycat applications, and malicious search engine advertisements designed to compromise private keys.

The setup portal directly validates the physical and programmatic integrity of your device. During the initial connection, it verifies official bootloader signatures and assists you in installing untampered firmware directly onto the onboard secure element. If the package was previously opened or if any unverified software exists, the setup utility alerts you instantly.

Crucially, trezor.io/start guides you through establishing your 12, 20, or 24-word offline recovery seed phrase. Because private keys are generated entirely in physical isolation on device microcontrollers, they never touch your operating system or network. Never photograph this phrase, enter it online, or type it into any website input field.
