6.1.1 Native Pluggable Authentication

MySQL includes a mysql_native_password plugin that implements native authentication; that is, authentication based on the password hashing method in use from before the introduction of pluggable authentication.

Note

As of MySQL 8.0.34, the mysql_native_password authentication plugin is deprecated and subject to removal in a future version of MySQL.

The following table shows the plugin names on the server and client sides.

The following sections provide installation and usage information specific to native pluggable authentication:

• Installing Native Pluggable Authentication

• Using Native Pluggable Authentication

For general information about pluggable authentication in MySQL, see Section 4.17, “Pluggable Authentication”.

Installing Native Pluggable Authentication

The mysql_native_password plugin exists in server and client forms:

• The server-side plugin is built into the server, need not be loaded explicitly, and cannot be disabled by unloading it.

• The client-side plugin is built into the libmysqlclient client library and is available to any program linked against libmysqlclient.

Using Native Pluggable Authentication

MySQL client programs use mysql_native_password by default. The --default-auth option can be used as a hint about which client-side plugin the program can expect to use:

$> mysql --default-auth=mysql_native_password ...
