How should i change ligin pattern

Hello,  am having challenges with my website login

I want my login to be: Login with your Email & Password only

Instead of login with id/username & password

How can i change it to login with your Email & Password

And also allow the text enter your email & password to appear to users on the form like facebook login

my website is www.ayoram.com please help

Login form is already accepting emails by default, all you need is to change language string to say "input email".
