A Trezor is a hardware wallet, a physical device designed to securely store and manage your cryptocurrency private keys, making it highly resistant to online hacking and malware. Trezor devices keep your private keys offline, enhancing security, while also offering features like transaction confirmation and online access through a compatible device.  

Trezor devices are the original, most trusted cryptocurrency hardware wallets. They are designed and marketed by Satoshi Labs. The primary function of a Trezor device is to serve as a hardware wallet for cryptocurrencies. They also have other security applications such as being used for second-factor authentication.
