Firebase rules only if user authenticated

Question

Is it possible only read,write if user authenticated in firebase?

Answer 1

Yes of course. First, select Firestore Database in the Firebase console, then select the Rules tab above.

and delete all the codes, paste the following codes there. Then publish it.

Here Cloud Firestore example:

rules_version = '2';
service cloud.firestore {
 match /databases/{database}/documents {
  match /{document=**} {
     allow read, write : if request.auth!=null;
  }
 }
}

You can also use this code for Firebase Storage. Here for more info: Firebase Security Rules
