IdentityProvider.Default

In this article, we will dive deep into the M code behind the IdentityProvider.Default function and explore its various components and how they work together.

Understanding IdentityProvider.Default

The IdentityProvider.Default function is a built-in function in Power Query that is used to provide authentication services to users who need to access data sources through Power Query queries. This function is called by default when a user creates a new query or when an existing query is refreshed.

The IdentityProvider.Default function takes several input parameters, including the credentials being used to authenticate the user and the type of authentication being used (e.g. OAuth, Windows, etc.). The function then returns a token that can be used to authenticate the user and access the data source.

The M Code Behind IdentityProvider.Default

The M code behind the IdentityProvider.Default function is a complex series of expressions and variables that work together to authenticate users and provide access to data sources. Here is a breakdown of the main components of the M code:

Step 1: Determine the Authentication Type

The first step in the M code is to determine the type of authentication being used. This is done by evaluating the authentication method specified in the query options. If no authentication method is specified, then the function defaults to Windows authentication.

Step 2: Retrieve the Credentials

The next step is to retrieve the credentials being used to authenticate the user. This is done by calling the CredentialRetrieval function and passing in the authentication type and any additional parameters required for the specific authentication method.

Step 3: Generate the Authentication Token

Once the credentials have been retrieved, the function generates an authentication token by calling the GenerateToken function and passing in the credentials and any additional parameters required for the specific authentication method. The authentication token is then returned to the user.

Step 4: Store the Authentication Token

The final step in the M code is to store the authentication token in the query settings. This is done by calling the SetQueryCredentials function and passing in the token and any additional parameters required for the specific authentication method.

The IdentityProvider.Default function is a critical component of Power Query that enables users to authenticate and access data sources. Understanding the M code behind this function is essential for developers and users who want to customize their authentication methods and integrate with other data sources.

By breaking down the M code into its component parts, we can see how the IdentityProvider.Default function works and how it can be customized for specific authentication scenarios. With this knowledge, developers and users can create more powerful and secure Power Query queries that meet their specific needs.
