# First Activation

> First device activation, firmware flashing via the configurator, and linking the device to a Melody account.

This page covers the **first activation** of a Melody device: flashing firmware via the configurator and linking the device to a Melody account.

During the first activation, the device sends its serial as part of a signed activation message and, on success, receives:

* **`system_token`** — used to continue setup and auth flows.
* **`factory_serial_id`** — a factory-provided identifier of the device. This field is mandatory but **not unique** across devices.
