No configuration is required, by default:
An API is available for developers to use autologin codes elsewhere in WordPress, e.g. push notifications, and to conditionally disable the plugin’s use. Code is published on GitHub, uses WordPress Plugin Boilerplate, conforms (mostly) to WordPress Coding Standards, and is unit & integration tested.
