When the {es} {security-features} are enabled, users must log in to {kib}
with a valid user ID and password.

{kib} also performs some tasks under the covers that require use of the
built-in `kibana_system` user.

. Configure {kib} to use the built-in `kibana_system` user and the password that you
created:

** If you don't mind having passwords visible in your configuration file,
uncomment and update the following settings in the `kibana.yml` file in your
{kib} directory:
+
--
TIP: If you installed {kib} using archive distributions (`zip` or
`tar.gz`), the `kibana.yml` configuration file is in `KIBANA_HOME/config`. If
you used package distributions (Debian or RPM), it's in `/etc/kibana`. For more
information, see {kibana-ref}/settings.html[Configuring {kib}].

For example, add the following settings:

[source,yaml]
----
elasticsearch.username: "kibana_system"
elasticsearch.password: "your_password"
----

Specify the password that you set with the `elasticsearch-setup-passwords`
command then save your changes to the file.
--

** If you prefer not to put your user ID and password in the `kibana.yml` file,
store them in a keystore instead. Run the following commands to create the {kib}
keystore and add the secure settings:
+
--
// tag::store-kibana-user[]
["source","sh",subs="attributes,callouts"]
----------------------------------------------------------------------
./bin/kibana-keystore create
./bin/kibana-keystore add elasticsearch.username
./bin/kibana-keystore add elasticsearch.password
----------------------------------------------------------------------

When prompted, specify the `kibana_system` built-in user and its password for these
setting values.  The settings are automatically applied when you start {kib}.
To learn more, see {kibana-ref}/secure-settings.html[Secure settings].
// end::store-kibana-user[]
--

. Restart {kib}. For example, if you installed
{kib} with a `.tar.gz` package, run the following command from the {kib}
directory:
+
--
["source","sh",subs="attributes,callouts"]
----------------------------------------------------------------------
./bin/kibana
----------------------------------------------------------------------
