Custom Login Portet In Liferay.

Sometimes liferay developer needs create custom login/signin protlet for their requirement. Here share my experience how one can create  custom login portlet in liferay.

Dowload the portlet form github

Step 1: jsp file >>> Replace the view.jsp file with the below code.
