I use xampp and with it came php my admin. Since I made a password for my localhost user I haven't been able to use it. I type localhost into my URL them on the left column click php my admin but it says "Error

MySQL said: Documentation
#1045 - Access denied for user 'root'@'localhost' (using password: NO)
phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server." how do I access it now?
