You clearly don't know what you are talking about. SQLite is a file on disk, the security of who can access it is managed by the OS via filesystem permissions, users and other mechanisms. It's not rocket science, and you would know that if you actually bothered to learn the basics. There is no "authentication" in SQLite, because it's not even applicable to what SQLite aims to be, which is an application file format. Would you also complain that there's no "authentication" on .json files?
