[MM3-users] How to change rest APi password

This is probably s stupid question but I have been searching for an answer.

How do you set a different rest api password?

The instructions say : The credentials are set in the [webservice] section of the configuration using the admin_user and admin_pass properties. But what is that referring to?

I am running docker, so is this in the docker.yaml file (I tried it there it did not work) or in the Django config file or someplace else?
