it might be because of socket authentication plugin:

In other words if you use "root" unix account you don't need password.
then he would have seen the "mysql" database in "show databases"

Thank you.
I noticed some anonymous user entries in mysql.user. I have executed the mysql_secure_installation and removed those users as well.

Check table mysql.user: you probably have the account '%'@localhost. It's a pattern, and rot@localhost matches. When running SHOW DATABASES you see only the databases which you have some permissions.

All,
When I tried to connect in centos 7 mariadb 10.2.11 server using root user, by mistake I gave wrong user name, but it connected successfully. I am not sure why. When I check show databases, it didnt list all DBs, but when I connect with root again, I can see all valid Dbs.
Is this normal that even if I give wrong user, it authenticate into DB server from root.
