MySQL account information is stored in the tables of the mysql database. This database and the access control system are discussed extensively in Database Administration, which you should consult for additional details.
Important: Some releases of MySQL introduce changes to the structure of the grant tables to add new privileges or features. Whenever you update to a new version of MySQL, you should update your grant tables to make sure that they have the current structure so that you can take advantage of any new capabilities. See mysql-upgrade.
MySQL Enterprise. In a production environment it is always prudent to examine any changes to users' accounts. The MySQL Network Monitoring and Advisory Service provides notification whenever users' privileges are altered. For more information see,

CREATE USER Syntax
CREATE USER user [IDENTIFIED BY [PASSWORD] 'password']
[, user [IDENTIFIED BY [PASSWORD] 'password']] ...
The CREATE USER statement was added in MySQL 5.0.2. This statement creates new MySQL accounts. To use it, you must have the global CREATE USER privilege or the INSERT privilege for the mysql database. For each account, CREATE USER creates a new record in the mysql.user table that has no privileges. An error occurs if the account already exists. Each account is named using the same format as for the GRANT statement; for example, 'jeffrey'@'localhost'. If you specify only the username part of the account name, a hostname part of '%' is used. For additional information about specifying account names, see GRANT Syntax.
The account can be given a password with the optional IDENTIFIED BY clause. The user value and the password are given the same way as for the GRANT statement. In particular, to specify the password in plain text, omit the PASSWORD keyword. To specify the password as the hashed value as returned by the PASSWORD() function, include the PASSWORD keyword. See GRANT Syntax.
DROP USER Syntax
DROP USER user [, user] ...
