Trezor App - Hardware #Wallet

Trezor Suite

Third party apps and Trezor

In addition to Trezor App, you can use your Trezor device with an increasing number of independent cryptocurrency wallets and online services. We believe that Trezor Suite is the best solution to manage your crypto assets, but there are some reasons you might choose to use your Trezor with a third-party wallet.

Please keep in mind that we do not develop nor maintain third-party software, so we cannot guarantee their full functionality. However, your private keys are always safely protected by your Trezor device, no matter what third-party application you use it with.

Third-party cryptocurrency wallets

Some third-party wallet interfaces let you connect your Trezor device and work with it. They do not hold any private keys. Instead, they display account balances and help you to manage transactions.

How does it work?

First, your Trezor contains a seed, 12 or 24 words that generate all the keys and addresses associated with your assets. That seed never leaves your device: when a transaction needs to be signed, the transaction data is sent into your Trezor, signed offline, and then passed back out. Using a third-party app, the exact same thing happens, but rather than Trezor Suite preparing the message data, the third-party app sends the message to your Trezor device. Since the Trezor can only accept a specific format, you don’t need to worry too much about which apps or extensions you connect to, as long as you use your Trezor to ensure that the transaction recipient address, amounts, and fees, are correct. This is where Trezor’s comes in — your Trezor screen will only ever show you the data that will be signed, so if a malicious attacker swaps the address for one of their own, or alters the amounts being sent, your Trezor will let you see that the data is not what you set so you can cancel the transaction.

Why use third-party applications?

Extra Features

Sometimes third-party applications are needed to access to dApps, staking, and more advanced features like multisignature (Multisig) with your Trezor. Additionally, in emergency situations you can recover your Trezor accounts with a third party application.

Recovering funds without a Trezor device

If your Trezor device gets lost or damaged, you can access your funds using your recovery seed and a third-party wallet. However, this should be used in emergencies only. To keep your funds safe at all times, we recommend getting a new Trezor device to recover your funds.
