I want to remove the password for user root in localhost. How can I do that? By mistake I have set the password of root user. That's why phpmyadmin is giving an error:

#1045 - Access denied for user 'root'@'localhost' (using password: NO)

You need to set the password for root@localhost to be blank. There are two ways:

1. The MySQL SET PASSWORD command:

   SET PASSWORD FOR root@localhost=PASSWORD('');
   

2. Using the command-line mysqladmin tool:

   mysqladmin -u root -pType_in_your_current_password_here password ''

I have also been through this problem,

First i tried setting my password of root to blank using command :

SET PASSWORD FOR root@localhost=PASSWORD('');

But don't be happy , PHPMYADMIN uses 127.0.0.1 not localhost , i know you would say both are same but that is not the case , use the command mentioned underneath and you are done.

SET PASSWORD FOR root@127.0.0.1=PASSWORD('');

Just replace localhost with 127.0.0.1 and you are done .
