An apology, I am not very knowledgeable about the subject and if I do not specify something, I will gladly let you know.
Attached image where when entering the MySql console tries to access a default account that is not 'root' is a user who had created at the beginning by mistake, and now I can not get rid of it. In fact I already change the name to the original and it does not match any account in the "mysql.user" table, but it keeps appearing by default when I enter MySql.
In advance Thank you very much!
