I am not sure if I understood your question correctly. If you want to create login form, that is not possible because we do not allow this type of forms.
Or you want to prepopulate email field? If so you can set default value inside of email field and set field property to be read only. This way your users will not be able to change it, but email address will always be the same.
You can also preopulate your form with our prepopulate app: http://prepopulate.jotform.io/
If I did not understood your question correctly please provide us more details abut what you are trying to achieve. Also your screenshot is not shown. Please added it again.
