At trezor.io/start, you can initiate the setup process for your Trezor hardware wallet. Begin by connecting your device to a computer or mobile device and following the on-screen instructions. Create a strong, unique PIN for device access and generate a secure recovery seed. This seed is crucial for restoring access to your wallet if your device is lost or damaged. Ensure you store this seed securely, preferably offline. Complete the setup by installing the Trezor Bridge or Trezor Suite software, depending on your device, to manage and monitor your cryptocurrency transactions with enhanced security features provided by Trezor.
