Power bi report server password update

Following up on this:

Although working with the API makes sense for some cases I found another solution.

1) I created a folder named 'Config'. In this I uploaded a blank report with only one datasource.

2) Every time the password needs to be changed, the password is only changed in this report.

3) Once the password is updated I run this script on the SQL db

/****** Update Password for ServiceUser ******

1) Go to https://<yoururl>/reports/manage/catalogitem/datasources/Config/ServiceUser and change the password
2  Run script

--> only updates password, if username changes uncomment section below 

******/
USE [pbiReportServer]
GO

/* declare variables */
DECLARE username VARBINARY(max);
DECLARE Anonymous VARBINARY(max);
DECLARE @ItemIds table (ItemId uniqueidentifier)

/* Select hashed username in ServiceUser report and set it to username */
SELECT username = Username FROM [pbiReportServer].[dbo].[DataModelDataSource] d
		LEFT JOIN CATALOG c ON d.ItemId = c.ItemID
		WHERE c.Name = 'ServiceUser'

/* Select hashed password in ServiceUser report and set it to Anonymous */
SELECT Anonymous = Password FROM [pbiReportServer].[dbo].[DataModelDataSource] d
		LEFT JOIN CATALOG c ON d.ItemId = c.ItemID
		WHERE c.Name = 'ServiceUser'

/* Select all items with selected username but ServiceUser Report  */
INSERT INTO @ItemIds
SELECT d.[ItemId]
FROM [pbiReportServer].[dbo].[DataModelDataSource] d
LEFT JOIN CATALOG c ON d.ItemId = c.ItemID
WHERE c.Name not like 'ServiceUser' and d.Username = username

/* Test before change */
--SELECT  'before change' as [Status], * FROM [pbiReportServer].[dbo].[DataModelDataSource]
--WHERE ItemId in (SELECT * FROM @ItemIds)

/* Update password for selected reports */
UPDATE [pbiReportServer].[dbo].[DataModelDataSource]
SET Password = Anonymous
WHERE ItemId in (SELECT * FROM @ItemIds)

/****** END - Also update username - END *******/
/* Update password for selected reports */
--UPDATE [pbiReportServer].[dbo].[DataModelDataSource]
--SET Username = username
--WHERE ItemId in (SELECT * FROM @ItemIds)

/****** END - Also update username - END *******/

/* Test after change */
--SELECT  'after change' as [Status], * FROM [pbiReportServer].[dbo].[DataModelDataSource]
--WHERE ItemId in (SELECT * FROM @ItemIds)

It selects all items where the usernamehash equals the one from the blank report and then updates the password hash
