Best practices for login pages?

Question

I am working on a single sign-on login page using Shibboleth that will be used for a variety of web applications. Obviously we would like to make this page as secure and usable

Answer 1

keeping the same design in your login page will let know your users they are attempting to log in to your page if design change randomly user may think the site has been moved, or they are being victims of pishing. so i would recomend to keep the same guidelines as your content pages
