MySQL includes two plugins that implement native authentication;
that is, authentication based on the password hashing methods in
use from before the introduction of pluggable authentication.
This section describes
which implements authentication against the
mysql.user table using the native password
hashing method. For information about
mysql_old_password, which implements
authentication using the older (pre-4.1) native password hashing
Section 7.1.2, “Old Native Pluggable Authentication”. For
information about these password hashing methods, see
Section 2.2.4, “Password Hashing in 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:
For general information about pluggable authentication in MySQL, see Section 5.9, “Pluggable Authentication”.
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
libmysqlclientclient library and is available to any program linked against
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:
shell> mysql --default-auth=mysql_native_password ...
