How to get Firebase user id for current firebase user

[spsarolkar]

I am logging into firebase using id token and I want to fetch userid for current user so that presence details can be obtained for the IOT device. How can I obtain the current user id.

Actually, you can get user UID instead of id.

You can get user uid string from FirebaseAuth object like this

auth.token.uid.c_str();

Note that this library uses MB_String class instead of Arduino String class which you can assign uid to the Arduino String like this.

String uid = auth.token.uid.c_str();
