What remains in the browser cache when authorizing through Apache?

Question

Apache HTTP Server

There is authorization through htaccess

AuthName "Authentication"
AuthType Basic
AuthUserFile /.htpasswd
require valid-user

Neither COOKIEs nor session are created during authorization.
How does the server understand that the user has logged in?
And how do I log out of my account?

header('WWW-Authenticate: Basic realm="Авторизация"');
header('HTTP/1.0 401 Unauthorized');

If you send the title, of course, a window will pop up asking you to enter a username and password, but if you refresh the page, then the authorization remains
