Trezor's security architecture is built on multiple layers of protection that work together to safeguard your private keys and transactions. Unlike software wallets, Trezor keeps your private keys completely isolated from any internet-connected device.
Recovery Seed Management
Your recovery seed is a 12 or 24-word phrase that can restore access to all your funds. During setup, Trezor generates this seed on the device itself, never exposing it to your computer. Write it down on the provided card and store it in a secure location. Never type it into a computer or take a digital photo of it.
PIN Protection
Your PIN is the first line of defense. Each incorrect attempt increases the wait time exponentially, protecting against brute-force attacks. Choose a PIN that's secure but memorable. Avoid sequences or patterns that could be guessed.
Passphrase Protection
For advanced users, Trezor supports passphrases—additional security layers that create a hidden wallet. Even if someone obtains your recovery seed, they won't access your hidden wallet without knowing the passphrase.
Transaction Verification
Every transaction must be approved on your Trezor device. You can verify the recipient address and amount on the device's screen before confirming. This protects against man-in-the-middle attacks and malware attempting to redirect your funds.
Physical Security
Keep your Trezor in a safe place. Consider a safety deposit box or home safe for significant holdings. Regular backups of your recovery seed ensure you can always restore your wallet if the device is lost or damaged.
