automatic updates - WordPress sites got auto upgraded

This question already has answers here: How exactly do automatic updates work? (3 answers) Closed 10 years ago.

With the release of WordPress 4.0.1 all my sites got auto upgraded even if none visited them and all those websites are behind browser authentication.

My sites are not broken but I am just curious to know how WordPress auto-upgrades the sites which are behind browser authentication.

• Now WordPress auto-upgrade itself for minor updates. You can disable it though if you want to. – Robert hue Commented Nov 21, 2014 at 7:08

In order for the update to occur, the site would have had to receive some form of traffic. Any traffic which loaded WordPress would do. Alternatively, anything which started the wp-cron.php process would trigger the update as well, like if you have it set to run that with a normal cron.
