When you create the database, you're asked whether you want to give everyone access (development mode), or whether no one gets it (production mode). If you choose the development mode, it will automatically disable that access after a certain timestamp, so you don't forget to update it before shipping. This of course doesn't stop people who don't care about security from just manually giving out public R/W, or extending the timestamp.
