You can create users/passwords for laravel outside of laravel using htpasswd. It's part of the HTTP specs. If you're currently using laravels auth, or any other auth system, you will probably never use it so ok to remove.
I use it for our testing servers so that the outside world can't view the site without our username/password, which is completely done at the server level and outside of laravel/php.
