Profile - user sign up

Hello may anyone can help me?
I have a sign up and sing in system in my app this is connected to firebase authentication and I’d like to set an icon profile so I created a page (profile) with page parameter (email and name) and in the icon profile I set open page but I cant set up the parameter because it is in diferent pages (sing up / in) the icon profile is in the initial page not in the sing in / up page
