Answer 2

Answer:

The correct answer to the given question is:

Sign-in

Explanation:

To recognize users across different devices, Sign-in that generates and sets unique IDs is required.

The User ID allows you to associate one or more sessions (as well as any activity within those sessions) with a unique and persistent ID that you send to Analytics. To use the User ID, you must be able to generate your own unique IDs, assign IDs to users consistently, and include these IDs wherever you send data to Analytics. You could, for example, send the unique IDs generated by your own authentication system to Analytics as User ID values. Any engagement that occurs while a unique ID is assigned, such as link clicks and page or screen navigation, can be sent and connected in Analytics via the User ID.
