Currently there are multiple places where you have to enter you ADF credentials. For instance:
All ADF Data Sources:

Storage Management Task for rolling up incremental data:

Transfer ODX to DWH

It would be nice to manage ADF instances/credentials on one central place, not on every single data source/task. ClientID/Secrets have a maximum lifespan of two years, which means a new secret has to be entered on multiple/many locations.
