I installed MySQL 5.6 on Windows, imported a database (as root), and created a new user with a password to access this database.
Connexion with the username and password does not work (tested with Workbench).
However, if I connect without password, login is accepted, but I don't see the database. Actually, this works with any username.
How do I connect with the newly created user? And how do I prevent connections with any username and no password, which look like a security issue?
