By default, Google Analytics can recognize returning users over multiple sessions from different browsers and devices. Is this statement true or false?

The statement is false. By default, Google Analytics uses cookies stored in the user's browser to recognize returning users. This means that if a user switches browsers or devices, Google Analytics will not be able to identify them as the same user since the cookies do not carry over across different platforms. Each browser and device registers as a new user unless the same account is used, and even then, without the specific implementation of User ID tracking or if the users are logged into a system where both browsers can share identity data, Google Analytics will treat these sessions separately. Therefore, the ability to recognize returning users is limited by the nature of how cookies work rather than any inherent capability of Google Analytics itself.
