User Name & Password dialog is not showing up when users try accessing the service portal


Description

User Name & Password dialog is not showing up when users try accessing the service portal url.

 

Resolution

When a user is trying to open "sp/?id=landing" page it will not show the user name and password field if the user is already logged in.
This is expected behavior and can be seen in OOB instances as well.
The URL might have been bookmarked, so when the logged-in user opens the URL, the landing page with no user name and password fields can be seen.
