Hi
are you or were you prompted to login? You will only see a log out button if you are using an authentication setting that requires login. So if you are using guest authentication then yes you or anyone else are automatically logged in as the guest user account.
You can change the authentication method via management but if you have been using the guest account until now then if you switch to another authentication method and a different username then you will not see the projects created as the guest user.
