PHP sessions work after browser reload?

Question

PHP

I read that sessions live only until the browser is restarted, and in fact it was like that on my site, until some time. After reinstalling Windows, I noticed that the site does not crash into the authorization window if you restart the browser (any), while the "Remember user" mode is turned off, i.e. session-only authentication is enabled. Is there any reason for this other than faulty code? OpenServer/PHP 7.1

Answer 1

Obviously, in the browser settings, uncheck the "start from the same place" checkbox.
But no one will do it anyway.
So fading a session in our time is possible only by timeout, and depends on the garbage collector killing old session files.

Answer 2

Of course, because cookies with the session id are saved.
