I'm hoping to use DockerHub with CircleCI to host private images and run builds. Right now, to do this, I have to put my DockerHub username and password in CircleCI, as explained here: https://circleci.com/docs/2.0/private-images/

Instead of this, is there a way to add an Auth token that I can share with CircleCI and not other applications? I'd rather not store my password in plain text everywhere.
