Hi @Sunju,
Have you cleared your session data after disabling the security plugin?
Have you rebooted your nodes after configuration changes?
Could you please share your `opensearch.yml` and `opensearch_dashboards.yml`
best,
mj

You can use a different browser or start a private (incognito) session.

@Sunju, I do not see you disabling the security plugin:
```auto
plugins.security.disabled: true
```

I removed security plugins. So, I got this error when I add that props.
```auto
java.lang.IllegalArgumentException: unknown setting [plugins.security.disabled] please check that any required plugins are installed, or check the breaking changes documentation for removed settings
```

Can you add `plugins.security.disabled: true` to your opensearch.yml and test once more.

I see, you have removed the plugin itself, I’ll run some tests in my lab and get back if Ill find a fix/reason for you.

I saw the guide that I need to remove plugin in the linked opensearch docs.
Thanks.

@Sunju, I have successfully removed the security plugin from Opensearch v2.9.0 using the instructions here:
[https://opensearch.org/docs/2.9/security/configuration/disable/](https://opensearch.org/docs/2.9/security/configuration/disable/) (these are for v2.9 rather than 2.16)
The cluster seems to be fine:
How did you deploy your cluster?
Best,
mj

I deploy tar.gz.
Did you just disable security or Remove plugins as well?

I`ve removed it as per the instructions. Have you removed anything using:
```auto
sudo bin/opensearch-dashboards-plugin remove
```

## Remove OpenSearch Dashboards plugin
The Security plugin is actually two plugins: one for OpenSearch and one for OpenSearch Dashboards. You can use the OpenSearch plugin independently, but the OpenSearch Dashboards plugin depends on a secured OpenSearch cluster.
If you disable the Security plugin in `opensearch.yml` (or delete the plugin entirely) and still want to use OpenSearch Dashboards, you must remove the corresponding OpenSearch Dashboards plugin. For more information, see [OpenSearch Dashboards remove plugins](https://opensearch.org/docs/2.9/install-and-configure/install-dashboards/plugins/#remove-plugins).

I Remove securityDashboards as above guide.
I think I always have the issue with capabilities api.
Should I configure anything about capabilities.
