Instructions:

MySQL password setup

mysql>show tables;

mysql>select * from user \G;

8.You can set your new password:

mysql> UPDATE mysql.user SET Password=PASSWORD('xxxx') WHERE User='root';
(where replace 'xxxx' with your new password)

Example:
mysql> UPDATE mysql.user SET Password=PASSWORD('muthu') WHERE User='root';

mysql> mysql -u root -p

enter password:*****

press Enter button.....




Navigate to the C:\wamp\apps\phpmyadminx.x.x\ folder. Inside that folder, open up config.inc.php

find in it: $cfg['Servers'][$i]['password'] = '';

and put your desired password.

Example:

$cfg['Servers'][$i]['password'] = 'YOUR_PASS';

replace YOUR_PASS with choosed password
