Answer 1

When you call firebase.auth() from the Admin SDK, you're getting an object of type Auth . As you can see from the API docs, it doesn't have a method called signInWithEmailAndPassword .

It seems you're mixing up the javascript client SDK with the Admin SDK. There's no reason to use the client SDK in Cloud Functions. It's supposed to be used in the browser only, since signing in only makes sense on the device that the user is actually using.

signInWithEmailAndPassword is only available in a browser environment. To get access to who made a particular request, you can use firebase.auth().getToken to get a JWT token, and send that along to your cloud function endpoint. Then from there you can call verifyIdToken to get the uid of whoever made the request.
