Authentication is any process by which you verify that someone is who they
5
claim they are. [1]_ Drizzle authentication is handled by plugins; there

are no grant or privilege tables.

Drizzle authentication is handled by plugins; by default there is no single
8
source where users are defined, such as a system user table, but each
9
authentication plugin will use different sources to verify the usernames
10
and passwords. (The plugin auth_schema does however keep users in a table inside
11
Drizzle, much like the familiar MySQL way of authenticating users works.).

*Choosing an authentication plugin, configuring it, and disabling all other
13
authentication plugins should be one of your first administrative tasks.*
15
One or more authentication plugins must be loaded, else no connections can
9
16
be made to Drizzle. On most systems, the :doc:`/plugins/auth_all/index`
10
17
plugin is loaded by default which, as its name suggests, allows all
11
18
connections regardless of username or password. (Some distributions enable
12
19
the :doc:`/plugins/auth_file/index` plugin by default instead).

The :doc:`/plugins/auth_schema/index` plugin first shipped with ``Drizzle 7.1
22
Beta 2011.10.28``. This plugin provides an authentication method that is
23
both secure and easy to use, and it is similar to how MySQL authentication
24
works so will be familiar to many users. If you don't know which authentication
25
plugin to use, you should start with configuring
26
:doc:`/plugins/auth_schema/index`. Likewise we warmly recommend distributors to
27
consider enabling this plugin by default.
