# Authentication method

Pentaho supports four authentication methods for connecting to the Azure SQL DB instance:

* **SQL Authentication**

  Connect using the Azure SQL Server username and password.
* **Azure Active Directory**

  Connect using Multi Factor Authentication (MFA). The MFA password must be entered on the displayed webpage.
* **Azure Active Directory with password**

  Connect using an Azure AD username and password.
* **Azure Active Directory with integrated authentication**

  Connect using the federated on-premises Active Directory Federation Services (ADFS) with Azure Active Directory in the cloud.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/install/10.2-install/pentaho-configuration/tasks-to-be-performed-by-a-pentaho-administrator/define-data-connections/enter-database-connection-information/connect-to-an-azure-sql-database/authentication-method-azure-sql-database.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
