Using different application master and simple master page

Scenario:
We wanted to have a more fancy master page for our login page, being the first page users hitting the site. Out of box login page uses Simple.master which is very basic, so we designed a new master page ( newsimple.master ). Now how to consume it.

Solution:
1. We could have back-up login page and point the exisiting one to new master page.
2. Another option is attaching the new master page using Web.Config, I will say this was much cleaner approach.
Navigate to 12HIVE > Templates > Layouts > Edit Web Config and add following lines in Web.Config

Code:

<configuration>
  <location path="login.aspx">
   <system.web>
     <pages masterPageFile="~/_layouts/newsimple.master" />
   </system.web>
 </location>
</configuration>
