When developing a HarmonyOS application, a developer receives the following product request: If a user logs in to the same HarmonyOS account on device A and device B, the user can log in to the app on device A and synchronize the application account authentication information to account B as needed. After the account authentication information is synchronized, the user can open the application on device B and log in directly without entering the application account authentication information again.
Which of the following descriptions of this scene is correct?

  1. The developer can do this with the help of UUIDs, because apps can use UUIDs to uniquely identify the same device during their lifetime
  2. If the developer borrows the UUID to achieve the above requirements, the UUID logo will still exist after the application is uninstalled.
  3. The developer can do this with the help of DVID, because the application can access and manage distributed devices based on the DVID
  4. If you use a DVID to achieve the above functions, the DVE is strongly associated with your HarmonyOS account and application information, so you can prevent other applications from accessing the current application data.
