Security primer (read this carefully)
The most important rule when using trezor.io/start and any hardware wallet is to treat your recovery seed as the absolute root of trust. The device stores your private keys and uses them to sign transactions — but if an attacker obtains your seed, they can recreate your wallet. Therefore, generate and store your seed offline, ideally on a durable metal backup. Never take photos or keep the seed in cloud storage. When installing Trezor Suite or firmware, confirm you are on the HTTPS trezor.io domain and check any checksums or fingerprint guidance provided by the vendor.
Another practical habit: always confirm transaction details on the Trezor device screen. The host computer is considered untrusted; malware on the host can alter the web or desktop UI. However, because the Trezor device displays the actual transaction to be signed, you can catch mismatches before approval. Use a PIN to protect the device against casual physical access, and for additional strong protection consider a passphrase (BIP39 passphrase) which creates hidden wallets accessible only with that passphrase.
When to update firmware
Update firmware only when the vendor publishes an official release on trezor.io/start or the official support channels. Firmware updates fix security issues and add features, but must be applied carefully and only via official sources. If you ever doubt an update, contact official Trezor support rather than third-party guides.
Recovery & emergency plan
Make a plan for disaster recovery: who (if anyone) should know where your backup is stored, and how funds should be retrieved if you lose access. Use multisig or custodial backups only if you understand the trade-offs. For most users, a single hardware wallet with a robust physical backup of the seed is sufficient.
This guide is a concise companion to the official trezor.io/start onboarding flow. It’s designed to be practical and actionable: download from the official site, initialize on-device, keep backups offline, and always verify on-device before signing. ¡Empieza con seguridad — toma las precauciones y mantén tu cripto a salvo!
