How to Reset Trezor Device via Trezor.io/Start


Resetting your Trezor device may be necessary if you forget your PIN, want to start fresh with a new wallet, or plan to give away or sell the device. Trezor.io/Start offers a secure way to walk through the process.

This guide explains how to reset your Trezor hardware wallet safely and correctly using the official setup interface.

When Should You Reset Your Trezor?

Resetting your Trezor is appropriate if:

  • You've forgotten your PIN and cannot access the wallet.
  • You want to create a brand new wallet from scratch.
  • You're selling or transferring the device to someone else.
  • You suspect that the wallet may have been compromised.
Important: Resetting your Trezor will permanently erase all stored private keys and wallet data. Only do this if you have your recovery seed or no longer need access to the existing wallet.

What You’ll Need

Before you begin, make sure you have the following:

  • Your Trezor Model One or Model T device.
  • A USB cable to connect the device to your computer.
  • Access to a trusted web browser (Chrome or Firefox recommended).
  • A secure computer and internet connection.
  • Optionally, your recovery seed if you intend to restore a previous wallet after reset.

Step-by-Step: Resetting Trezor via Trezor.io/Start

Step 1: Visit the Official Site

Go to Trezor.io/Start. This is the official Trezor setup and management page. Select your device model (Model One or Model T) when prompted.

Step 2: Connect Your Device

Use the USB cable to connect your Trezor device to your computer. Make sure the connection is stable.

Step 3: Wait for Detection

Your device should be recognized automatically. If prompted, install or open Trezor Suite or ensure that Trezor Bridge is running if using the browser version.

Step 4: Access Device Settings

If the device is already initialized (i.e., has been set up before), you will see the wallet dashboard. From here:

  • Open Device Settings.
  • Scroll down and look for the “Factory Reset” or “Wipe Device” option.

Step 5: Confirm Reset on Device

When you select the reset option, a confirmation message will appear both on your computer screen and on the Trezor device. You must confirm the action physically on the device to proceed.

This step is essential to prevent accidental or remote resets.

Step 6: Device Wipes All Data

Once confirmed, your Trezor will erase all stored wallet information, including private keys, PIN, passphrases, and settings. It will return to the uninitialized state—just like when it was brand new.

Step 7: Return to Trezor.io/Start

After the reset is complete, return to Trezor.io/Start to begin setup. You can now:

  • Create a new wallet if you want to start fresh, or
  • Recover an existing wallet using your 12- or 24-word recovery seed.

Alternative Method: PIN Fail-Safe Reset

If you forgot your PIN, Trezor includes a built-in safety feature:

  • Each incorrect PIN entry introduces a time delay before you can try again.
  • After 16 failed PIN attempts, the device will automatically wipe itself to protect your wallet from brute-force attacks.

This is an automatic reset, and you’ll need your recovery seed to restore your funds afterward.

What Happens After Reset?

Once the device is reset:

  • All previous data is gone.
  • You can set up the device as new or restore an old wallet.
  • If you had funds on the device, they can only be recovered by entering the correct recovery seed during restoration.

Safety Tips

  • Always verify that you are on the correct website (Trezor.io/Start) to avoid phishing.
  • Never enter your recovery seed on any website or type it into your computer.
  • Reset your device only when necessary and always confirm actions on the device screen.
  • If disposing of the device, reset it first to remove all personal data.

Final Thoughts

Resetting your Trezor device via Trezor.io/Start is a straightforward process, but it should be done carefully. Whether you're starting over or passing the device to someone else, a proper reset ensures your wallet is clean and secure. Always back up your recovery seed before wiping your device to avoid permanent loss of access to your funds.
