Accessing multiple InfluxDB databases on the same server

Hi,

We have an InfluxDB server hosting multiple different databases for different parts of the application.
We also have a grafana user which is able to read all those databases.

Do I really need to specify a separate data source for each and every database?
(That especially means that if I ever want to change the password for the influx user I need to touch each and every data source.)

Is there an easier way?

Not currently. A Grafana InfluxDB data source can currently only target a single database
