Normally, the only time you see the log in page is when you are logged out, but when you log out, you no longer have access to the editor. To be able to edit the log in page, do not log out of the portal.
To edit the log in page:
1.
Open the portal you want to edit and click the Home tab.
2.
Click Edit.
3.
In the browser address bar, edit the portal URL and change it from http://... /Default.aspx to http://... /login.aspx
This opens the log in page without having to log out.
