Auto Update is built for site owners who want WordPress to stay current without logging in to run updates manually.
It keeps WordPress core, plugins, and themes updated automatically, which helps reduce maintenance work, apply security fixes sooner, and keep the site closer to the latest stable releases.
Once activated, it enables both minor and major core updates and allows installed plugins and themes to update in the background.
There is no settings page. Activate the plugin and let WordPress handle updates automatically.
