Changer son mot de passe MySQL

On peut changer facilement son mot de passe depuis phpmyadmin:

en ligne de commande:

SET PASSWORD FOR monty@host = password( 'new_password' ); 

mysql -u root -p
use mysql;
update user set password=PASSWORD("NEWPASSWORD") where User='lambda';

vous avez perdu le password root et vous ne voulez pas réinstaller mysql en faisant un backup des tables? rien de plus simple
