Firebase Rules: How to block anonymous access?











up vote

Reading the Firebase Rules Documentation I couldn't find anything on how to block anonymous access to a specific collection or document.



In other words, I want to block users who are not logged in, and I also want to block users who are logged in as anonymous. I want to allow only users who are logged in as themselves (through email, Facebook, Google, SMS, etc).



How can I do that?



This is the code I came up with, which doesn't work:



    service cloud.firestore {
match /databases/{database}/documents {
}
match /collectionExample/{documentExample} {
allow create: if request.auth.uid != null && request.auth.token.isAnonymous != false;
allow read: if request.auth.uid == resource.data.userId;
}
}
}

          I haven't tried this, but I suspect you can use request.auth.token.firebase.sign_in_provider (see the docs for auth). It's supposed to contain the value anonymous for anonymous auth. So, to allow document creates for non-anonymous logged in users:



          allow create: if request.auth.uid != null && request.auth.token.firebase.sign_in_provider != 'anonymous';


          Or, you could change it to only allow certain providers as well, given the other possible values for token firebase.sign_in_provider in the docs.
