title: How do I set Firebase's 'Realtime Database' rules?
body: <p>Simple question: Is there any problem with setting the 'read' and 'write' rule on my Realtime Database (Firebase) to 'true' (no authentication) if the user is <strong>just reading</strong> data from the database and <strong>not writing</strong> anything to it and there's no secret data stored in this database, that the user isn't supposed to see?</p>
