Trezor is a cryptocurrency hardware wallet that enables users to store their digital assets offline in so-called cold storage. In other words, the private keys that grant access to a user’s cryptocurrency are generated and stored on the Trezor device and never leave it.
This makes Trezor an ideal tool for securely storing cryptocurrencies, especially in large amounts.
Trezor was originally designed for storing Bitcoin, but it has since been updated to support a wide range of other cryptocurrencies, including Ethereum. In this article, we will take a look at how Trezor works with Ethereum and whether or not it is a good idea to store your ETH on a Trezor device.
Trezor uses what is known as a “seed” to generate the private keys that give access to a user’s cryptocurrency. This seed is generated randomly when the Trezor is initialized and it can be used to generate an infinite number of private keys.
The seed is also used to generate a recovery phrase that can be used to restore the Trezor in case it is lost or damaged.
The seed is generated by the Trezor device and never leaves it. This means that even if your Trezor is stolen, the thief would not be able to access your cryptocurrency without also knowing the seed.
The seed is also encrypted and stored on the Trezor device itself, so even if someone were to physically gain access to your Trezor, they would not be able to extract the seed without also knowing your Trezor PIN code.
The Trezor device also includes a number of security features such as a passphrase protection and two-factor authentication. The passphrase protection allows you to set an additional password that must be entered before the device will reveal the seeds or private keys.
The two-factor authentication requires you to confirm any actions on the device with your smartphone via an app such as Google Authenticator.
In short, yes, Trezor can be used to store Ethereum safely and securely. The seed never leaves the device and all private keys are generated offline in cold storage.
Additionally, the passphrase protection and two-factor authentication add an extra layer of security on top of the already robust security provided by the Trezor hardware itself.
