All content in AdtUXShowcase is public and does not require authentication. This page's content is an example of the default Login page (provided by LibADT) for an application that requires a login. The menu bar would normally not contain any menu links except possibly the support icon, until the user is logged in.
If you choose to hide the accessibility banner, you won't be able to see it anymore, unless you clear your browsing history and data.
