False. By default, Google Analytics uses cookies stored in a specific browser on a specific device to identify users. If a user switches browsers or devices, Google Analytics will treat them as a new user because the cookies from their previous session are not present. To recognize users across multiple browsers and devices, you need to implement more advanced techniques like User-ID tracking or Google Signals, which link user activity to a persistent ID. Without these, the default cookie-based tracking is limited to a single browser on a single device.
