iOS Login Form Autofill

I have a login form on our website. iOS use to autofill the form as soon as it loaded the page. A couple of iOS version ago, that stopped. Now you have to tap in the username field and then press the Autofill Password link above the keyboard.

Many forms I go to, my info fills in as soon as the page loads.

Does anyone know how to set the form to make it autofill without having to press autofill?
