Advanced conditions with the request

In the previous article I created an example where I’ve shown you how to use request object to get information about uid of the requested user. Now I’m going to show you more available properties in incoming request.

• email — email address
• email_verified — information about the verified e-mail address
• firebase.identities — map of user identities
