Note, however, that the ability to change the passwords of other users is restricted to those user accounts that have been granted UPDATE privileges on the mysql database When setting a password using the IDENTIFIED BY clause of the GRANT or CREATE USER commands, or via the mysqladmin tool, MySQL will automatically encrypt the password string for you However, this does not apply to passwords set with the SET PASSWORD command, which requires you to manually encrypt the password Therefore, the following three commands are equivalent:

Passwords are stored in the Password field of the user grant table, and are encrypted with the MySQL PASSWORD() function When a user logs in to the MySQL server and provides a password, MySQL first encrypts the supplied password string using the PASSWORD() function, and then compares the resulting value with the value in the Password field of the corresponding user record in the user table

C autioN The PASSWORD() function in MySQL 41 and later generates a longer,
41-byte hash value that is not compatible with older versions (which used a 16-byte value) Therefore, when you upgrade a pre-41 MySQL server installation to MySQL 41 or better, you must run the mysql_fix_privilege_ tables script in the scripts/ directory of your MySQL installation to update the grant tables so they can handle the longer hash value
The Administrator Password
For both UNIX and Windows systems, when MySQL is first installed, the administrative account root@localhost is initialized with an empty password This default setting implies that any one could log in as root without a password, and would be granted administrative privileges on the server Needless to say, this is a significant security hole To rectify this, set a password for root@localhost as soon as possible using any of the following commands:
[root@host]# /usr/local/mysql/bin/mysqladmin -u root password 'secret' mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('secret');
This password change goes into effect immediately, with no need to restart the server or reload the grant tables If you later forget the password for root@localhost and are locked out of the grant tables, take a deep breath, and then follow these steps to get things up and running again: 1 Log in to the system as the system administrator (root on UNIX) and stop the MySQL server This can be accomplished via the mysqlserver startup and shutdown script in the support-files/ directory of your MySQL installation, as follows:
[root@host]# /usr/local/mysql/support-files/mysqlserver stop
On UNIX systems that come with MySQL preinstalled, an alternative is to stop (and start) MySQL with the /etc/rcd/initd/mysqld scripts 2 Start MySQL again with the special --skip-grant-tables startup option
[root@host]# /usr/local/mysql/bin/safe_mysqld --skip-grant-tables -skip-networking
This bypasses the grant tables, enabling server login as the MySQL root user without providing a password The additional --skip-networking option tells MySQL not to listen for TCP/IP connections and ensures that no one can break in over the network while you are resetting the password

Managing Users and Controlling Access
3 Use the SET PASSWORD command, as described in the preceding section, to set a new password for the MySQL root user:
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('secret');
4 Log out of the server, stop it, and restart it again in the normal manner:
[root@host]# /usr/local/mysql/support-files/mysqlserver stop [root@host]# /usr/local/mysql/support-files/mysqlserver start
This procedure should reset the password for the root@localhost account and permit logins with the new password set in step 3
