How to make the realtime database more secure

Hi,
I am using the firebase realtime database and authorisation in my app. Currently my database rules are:
{
“rules”: {
“.read”: true,
“.write”: true,
}
}

This is fine for testing but I want to make it more secure for when I release my app. Any advice on how to do this?
