Missing Logout Button/Menu in the Webbrowser


now I new here and I will test SonarQube (developer for my projects. So i’ve installed a server on Linux and check the function from Windows 10.
After first configuration I will login with an other user as admin and I missing the logout menu point in the firefox browser. After reopen of the firefox and connect to my SonarQube server I’m autamtic logged in as admin. That is not so good.
I tested it also on my Linux machine with login a created user. And here is the same behaviour. After restart from firefox and open the web page from my server I auto logged in as the created user.

The same result is on Windows10 with the edge browser.

How can I log out on the web page?
