Answer 1

You should check the auth variable.

To define the security rules that allow write access to all the locations by this email address firebaseowner@gmail.com only:

{
  "rules": {
    ".read": true,
    ".write": "auth != null && auth.token.email == 'firebaseowner@gmail.com'"
  }
}

To define the security rules that allow write access to only the location /users by this email address firebaseowner@gmail.com only:

{
  "rules": {
    ".read": true,
    "users": {
      ".write": "auth != null && auth.token.email == 'firebaseowner@gmail.com'"
    }
  }
}
