Or operator '||' not working in firebase rules

Question

I'm trying to change my firebase realtime database rules so that I can access it from both authenticated and unauthenticated users, I changed them to

{
  "rules": {
    ".read": "auth == null",
    ".write": "auth != null" ||"auth==null"
  }
}

But the or operator || is not working. What should I do?

Thanks!

I think you need to quote the whole expression: `"a || b"`, in your case you can simply use `".write": true`, see https://firebase.google.com/docs/database/security/ — , Dec 26 '16 at 06:27

Try This

{
    "rules:{
        ".read": "auth == null",
        ".write": "auth != null || auth==null"
    }
}

Also, If you want to allow both users authenticated and non-authenticated , it means you want to allow all users to access database, then you can do this :

These rules give anyone, even people who are not users of your app, read and write access to your database

{ "rules": { ".read": true, ".write": true } }
