# Configure Dashboards sign-in for multiple authentication options
|
||||
|
||||
You can configure the sign-in window for OpenSearch Dashboards to provide either a single option for authenticating users at sign-in or multiple options. Currently, Dashboards supports basic authentication, OpenID Connect, and SAML as the multiple options.
|
||||
|
||||
## General steps for configuring multiple authentication options
|
||||
|
||||
Consider the following sequence of steps before configuring the sign-in window for multiple authentication options.
|
||||
|
||||
1. Decide which types of authentication to make available at sign-in.
|
||||
1. Configure each authentication type, including an authentication domain for the identity provider (IdP) and the essential settings that give each type sign-in access to OpenSearch Dashboards. For OpenId Connect backend configuration, see [OpenID Connect]({{site.url}}{{site.baseurl}}/security-plugin/configuration/openid-connect/). For SAML backend configuration, see [SAML]({{site.url}}{{site.baseurl}}/security-plugin/configuration/saml/).
|
||||
1. Add, enable, and configure multiple option authentication settings in the `opensearch_dashboards.yml` file.
|
||||
|
||||
## Enabling multiple authentication options
|
||||
|
||||
By default, Dashboards provides basic authentication for sign-in. To enable multiple options for authentication, begin by adding `opensearch_security.auth.multiple_auth_enabled` to the `opensearch_dashboards.yml` file and setting it to `true`.
|
||||
|
||||
To specify the multiple authentication types as options during sign-in, add the `opensearch_security.auth.type` setting to the `opensearch_dashboards.yml` file and enter multiple types as values. When more than one authentication type is added to the setting, the Dashboards sign-in window recognizes multiple types and adjusts to accommodate the sign-in options.
|
||||
|
||||
When setting up Dashboards to provide multiple authentication options, basic authentication is always required as one of the values for the setting.
|
||||
{: .note }
|
||||
|
||||
Add a single value to the setting when only one authentication type is needed.
|
||||
|
||||
```yml
|
||||
opensearch_security.auth.type: "openid"
|
||||
```
|
||||
|
||||
For multiple authentication options, add values to the setting as an array separated by commas. As a reminder, Dashboards currently supports a combination of basic authentication, OpenID Connect, and SAML as a valid set of values. In the setting, these values are expressed as `"basicauth"`, `"openid"`, and `"saml"`.
|
||||
|
||||
```yml
|
||||
opensearch_security.auth.type: ["basicauth","openid"]
|
||||
opensearch_security.auth.multiple_auth_enabled: true
|
||||
```
|
||||
|
||||
```yml
|
||||
opensearch_security.auth.type: ["basicauth","saml"]
|
||||
opensearch_security.auth.multiple_auth_enabled: true
|
||||
```
|
||||
|
||||
```yml
|
||||
opensearch_security.auth.type: ["basicauth","saml","openid"]
|
||||
opensearch_security.auth.multiple_auth_enabled: true
|
||||
```
|
||||
|
||||
When the `opensearch_security.auth.type` setting contains `basicauth` and one other authentication type, the sign-in window appears as in the following example.
|
||||
|
||||
<img src="{{site.url}}{{site.baseurl}}/images/Security/OneOptionWithoutLogo.png" alt="Basic authentication and one other type in the sign-in window" width="350">
|
||||
|
||||
With all three valid authentication types specified, the sign-in window appears as in the following example.
|
||||
|
||||
<img src="{{site.url}}{{site.baseurl}}/images/Security/TwoOptionWithoutLogo.png" alt="All three authentication types specified in the sign-in window" width="350">
|
||||
|
||||
## Customizing the sign-in environment
|
||||
|
||||
In addition to the essential sign-in settings for each authentication type, you can configure additional settings in the `opensearch_dashboards.yml` file to customize the sign-in window so that it clearly represents the options that are available. For example, you can replace the label on the sign-in button with the name and icon of the IdP. Refer to the settings and descriptions that follow.
|
||||
|
||||
<img src="{{site.url}}{{site.baseurl}}/images/Security/TwoOptionWithLogo.png" alt="Multi-option sign-in window with with some customization" width="350">

||||
|
||||
### Basic authentication settings
|
||||
|
||||
These settings allow you to customize the basic username and password sign-in button.
|
||||
|
||||
Setting | Description
|
||||
:--- | :--- |:--- |:--- |
|
||||
`opensearch_security.ui.basicauth.login.brandimage` | Login button logo. Supported file types are SVG, PNG, and GIF.
|
||||
`opensearch_security.ui.basicauth.login.showbrandimage` | Determines whether a logo for the login button is displayed or not. Default is `true`.
|
||||
|
||||
### OpenID Connect authentication settings
|
||||
|
||||
These settings allow you to customize the sign-in button associated with OpenID Connect authentication. For the essential settings required to use OpenID Connect as a single sign-in option, see [OpenSearch Dashboards single sign-on]({{site.url}}{{site.baseurl}}/security-plugin/configuration/openid-connect/#opensearch-dashboards-single-sign-on).
|
||||
|
||||
Setting | Description
|
||||
:--- | :--- |:--- |:--- |
|
||||
`opensearch_security.ui.openid.login.buttonname` | Display name for the login button. "Log in with single sign-on" by default.
|
||||
`opensearch_security.ui.openid.login.brandimage` | Login button logo. Supported file types are SVG, PNG, and GIF.
|
||||
`opensearch_security.ui.openid.login.showbrandimage` | Determines whether a logo for the login button is displayed or not. Default is `false`.
|
||||
|
||||
### SAML authentication settings
|
||||
|
||||
These settings allow you to customize the sign-in button associated with SAML authentication. For the essential settings required to use SAML as a sign-in option, see [OpenSearch Dashboards configuration]({{site.url}}{{site.baseurl}}/security-plugin/configuration/saml/#opensearch-dashboards-configuration).
|
||||
|
||||
Setting | Description
|
||||
:--- | :--- |:--- |:--- |
|
||||
`opensearch_security.ui.saml.login.buttonname` | Display name for the login button. "Log in with single sign-on" by default.
|
||||
`opensearch_security.ui.saml.login.brandimage` | Login button logo. Supported file types are SVG, PNG, and GIF.
|
||||
`opensearch_security.ui.saml.login.showbrandimage` | Determines whether a logo for the login button is displayed or not. Default is `false`.
|
||||
|
||||
## Sample setup
|
||||
The following example shows basic settings in the `opensearch_dashboards.yml` file when it is configured for two types of authentication at sign-in.
|
||||

||||
