# Cync

> Cync is a built-in integration for Home Assistant. It has 1.3k installs sharing analytics and needs the vendor's cloud.

Cync is a built-in integration that connects Cync lights to Home Assistant through the vendor's cloud. It adds light entities, so the lights can be controlled from Home Assistant alongside other devices. Setup happens in the user interface and asks for the email address and password of a Cync account. A two-factor code sent to the account's email is requested as part of signing in. Because it relies on the vendor's cloud, an internet connection is needed for it to work.
