Change the default login page of SharePoint 2013 web application

I had to change the default login page for SharePoint 2013 web application because I am using a Claim based authentication for my web application with a custom login page.

It looks really simple but it really helped me a lot for the customization.

Set-SPCustomLayoutsPage -Identity "Login" -RelaivePath "/_layouts/custompages/customLogin.aspx" -WebApplication "{replace with web app url}"

I hope it helps.
