An anonymous user in Firebase Authentication is not much more then their UID.

When you uninstall an app or wipe the device, that UID is wiped from the device. When the user signs in with anonymous authentication next time, they will get a new UID. There will be no connection between their previous UID and the new UID. This is the nature of anonymous authentication.

The information on the original UID will still exist on the Firebase servers, but there's no built-in way to connect the former UID and the next UID together.
