For most of the authentication protocols it supports, Firebase doesn't store user data anywhere. Even for the protocols where it does store data (I only know of email+password doing this), it stores this information in a place that your application can't access (though you can find those users in the dashboard of your Firebase).

To quote the Firebase documentation:

It does not store profile or user state in your Firebase. To persist user data you must save it to your Firebase.

What most applications end up doing, is keeping a list of users inside their Firebase that they manage themselves. So when a user first authenticates with the application, it creates a node under /users/ that contains the information for that user.

See this section of the Firebase documentation that describes storing user data.
