Power bi report server password update
You would have to write a script to loop through all your data sources and update the password one by one. You should be able to do this with Powershell using the Report Services Powershell Tools (https://github.com/microsoft/ReportingServicesTools) or if you want to use another scripting language you could access the REST api directly (see https://app.swaggerhub.com/apis/microsoft-rs/PBIRS/2.0)
