PIN: Choose a unique PIN and never share it.
Recovery seed: Write it down offline, in order, and store it in a secure place (two copies in different locations is ideal).
Passphrase (optional): Consider using a passphrase only if you understand its implications — it acts as a 25th seed word.
Official sources: Only use official Trezor domains and verified downloads; watch for phishing.
Device safety: Never enter your recovery seed into a computer or phone. The device is built so private keys never leave it.
