1 By default, a MariaDB installation has an anonymous user, allowing anyone
2 to log into MariaDB without having to have a user account created for
3 them.  This is intended only for testing, and to make the installation
4 go a bit smoother.  You should remove them before moving into a
5 production environment.

5  ... Success!

1 By default, MariaDB comes with a database named 'test' that anyone can
