It is the way MySQL authenticates and current users installed.

When you run this command

SELECT USER(),CURRENT_USER();

you quickly learn that USER() tells you how mysqld sees you trying to login and CURRENT_USER() tells you how mysqld allowed you to login. I discussed this 3 years ago in Why does OS login not exist in the user table, but I can still login to MySQL?

My guess is that whatever CURRENT_USER() is in mysql.user has no password.

You can run SELECT CONCAT(QUOTE(user),QUOTE(host)) userhost,password FROM mysql.user; to see your users. You might note that password is blank.

To solve your issue, you must create a remote username and password.
