Hi Joe,

Nice article. I have a question-

How does Firebase defines a unique user? How will Firebase know that its a same user when a user uninstalls and reinstalls an app on a device? Or when a user installs app on multiple devices?

Also what happens when I login to different accounts on a same device?

Thanks

Abhishek
