The CREATE USER statement creates new MySQL accounts. An error occurs if you try to create an account that already exists.

To use CREATE USER, you must have the global CREATE USER privilege or the INSERT privilege for the mysql database. When the read_only system variable is enabled, CREATE USER additionally requires the SUPER privilege.

For each account, CREATE USER creates a new row in the mysql.user table with no privileges and (as of MySQL 5.5.7) assigns the account an authentication plugin. Depending on the syntax used, CREATE USER may also assign the account a password.

Each user_specification clause consists of an account name and information about how authentication occurs for clients that use the account. This part of CREATE USER syntax is shared with GRANT, so the description here applies to GRANT as well.

Each account name uses the format described in Section 6.2.3, “Specifying Account Names”. For example:

CREATE USER 'jeffrey'@'localhost' IDENTIFIED BY 'mypass';

If you specify only the user name part of the account name, a host name part of '%' is used.

The server assigns an authentication plugin and password to each account as follows, depending on whether the user specification clause includes IDENTIFIED WITH to specify a plugin or IDENTIFIED BY to specify a password:


IDENTIFIED WITH is available as of MySQL 5.5.7. Before 5.5.7, authentication plugins are not used, so only the remarks about IDENTIFIED BY apply.

If the account has no password, the Password column in the account's mysql.user table row remains empty, which is insecure. To set the password, use SET PASSWORD. See Section, “SET PASSWORD Syntax”.

If the server assigns no plugin to the account, the plugin column in the account's mysql.user table row remains empty.

For client connections that use a given account, the server invokes the authentication plugin assigned to the account and the client must provide credentials as required by the authentication method that the plugin implements. If the server cannot find the plugin, either at account-creation time or connect time, an error occurs.

If an account's mysql.user table row has a nonempty plugin column:

If an account's mysql.user table row has an empty plugin column:

For additional information about setting passwords and authentication plugins, see Section 6.3.5, “Assigning Account Passwords”, and Section 6.3.6, “Pluggable Authentication”.


CREATE USER may be recorded in server logs or on the client side in a history file such as ~/.mysql_history, which means that cleartext passwords may be read by anyone having read access to that information. For information about password logging in the server logs, see Section, “Passwords and Logging”. For similar information about client-side logging, see Section, “mysql Logging”.
