| # - You can set a password for root accounts. | |
| # - You can remove root accounts that are accessible from outside the local host. | |
| # - You can remove anonymous-user accounts. | |
| # - You can remove the test database (which by default can be accessed by all users, even anonymous users), | |
| # and privileges that permit anyone to access databases with names that start with test_. | |
