How does it work?
Trezor is a small single-purpose computer. It is designed to protect your private keys from possible online and offline risks. To do this, Trezor keeps the private keys away from the Internet and confirms the transactions in-device. That way, you can always check the screen for the right address, amount and transaction fee before sending your bitcoins.
In layman's terms, you can connect Trezor to an infected computer and still be able to have 100% control over the funds in your device.

Sign & Verify messages
It is also possible to sign and verify messages using Trezor:
Backup and recovery
When first activating the device, you are asked to write down the recovery seed phrase.
This means that in case your Trezor is lost or stolen you can easily retrieve your funds another Trezor or any other compatible wallet.
Advanced Settings - Passphrase

You can use Trezor as your second-factor authentication (U2F) token with services such as Google, GitHub or Dropbox. A further advantage of Trezor is that its users can truly verify what they are about to authorize on the device display.
- Password Manager
The Trezor Password Manager allows users to manage all their passwords and digital identity with the Trezor security and encryption. The Trezor Password Manager does not require remembering one master password, as access is granted by pressing a physical button on your Trezor device. Your passwords are stored on Dropbox or Google Drive in an encrypted form using the private keys derived and safely stored in your Trezor.
- SSH login
With the Trezor SSH Agent, administrators can enjoy passwordless and secure authentication to their servers.
