Always begin at trezor.io/start. This link leads you to verified Trezor Suite installers and prevents accidental use of counterfeit downloads. The guide there will walk you through firmware checks, PIN creation, and seed generation.
The Suite connects to your device to display account balances, build transactions, and coordinate signing. The private keys remain on-device; Suite acts as your secure control panel.
Use a strong PIN, an offline recovery seed stored physically (metal recommended), and enable passphrases only if you understand their implications. Verify firmware updates only via Suite after visiting trezor.io/start.
Using trezor.io/start establishes a verified chain-of-trust from the download to the hardware confirmation on your device. It minimizes risks from phishing, tampered installers, and fraudulent guides — and it's the recommended first action for new Trezor users.
