After you select the user whose password you want to change, you can use the following command to change the password:

ALTER USER 'username'@'host' IDENTIFIED BY 'new_password';

Where, 'username' and 'host' is the username and host address you want to change the password for, and new_password is the new password you want to set. After executing this command, MySQL will update the user's password.
