Begin by connecting your Trezor device—Model One or Model T—to your computer using the USB cable. Ensure the cable is firmly attached and that your device powers on.
Next, launch the Trezor Suite application installed on your system. You can use the desktop app for maximum security or access the browser version if preferred. The Suite automatically detects your connected device.
When prompted, enter your PIN using the randomized keypad. This approach prevents keyloggers or malware from tracking your input. Your PIN is unique to your device and is required each time you log in.
