Trezor Model T Setup

This article details how to set up (initialize) your Trezor Model T hardware wallet for use with Casa App.

To begin, verify the integrity of the device box and the device to ensure that it is free from tampering.

Once your Trezor Model T has been unboxed, remove the tamper seal and head over to wallet.trezor.io in your browser. We recommend Firefox, Brave, or Chrome. You’ll connect your Trezor Model T device when prompted, using the provided cord.

If your device is not recognized once plugged in, head over to wallet.trezor.io/#/bridge to download the bridge.

If this is your first time setting up this device, you'll likely be asked to do a firmware update.

Next up, choose “Create Wallet”, and then select “Create with Single Backup”. Accept the terms & conditions, and confirm the action on your device by holding down your finger on the touch screen.

Now, you’ll need to complete the backup process. Choose “Create a backup in 3 minutes”, click the box, and press continue.

During this backup process, you’ll be prompted to write down the 12 word seed phrase.

Backup Process
 
While Casa enables a fully seedless setup, Trezor will check that you've written these down properly by quizzing you afterward. Because of this, use the provided card to write the 12 word seed to use it as a reference for the “seed phrase quiz” on the device,
 
Once the quiz is complete, you can then destroy the card with the seed phrase (but keep your device safely stored).
 
Your seed phrase is a copy of your private key. If at any point you believe it may have been compromised, you must complete a key rotation to regain full security.
 
Use the device touch screen to scroll through each word on the device, writing them down for confirmation in the next step. Once all 12 words have been written, complete the quiz on the device.

Next, you’ll set the PIN code on your Trezor. It’s very important that you do not forget this! The Trezor Model T will perform a factory reset after 16 failed PIN attempts.
 
If you are using multiple hardware wallet devices in your multisig setup, we recommend using the same a 4-8 character PIN (no zeros) across all your hardware devices, and saving it in a password manager.

Now, you’ll be asked to name your device. You can choose any name, though for best OpSec practices, we recommend not choosing words such as, “Casa” or “multisig."

The final steps will ask you to set up bookmarks, newsletter & social media with Trezor, but those steps you may click through to skip them.

That’s it! Your Trezor Model T is now initialized and ready to be added to your mutlisig keyset in Casa App.

Finally, keep your Trezor somewhere safe and secret. Though there may not be funds in the wallet yet, keeping it secure and protected from tampering prior to funds placement is very important!
