Modal Signup

I am trying to use a modal or login/signup page where user can define their password directly into the form (not via email later no).
I have seen this topic :
https://ww.wp.xz.cn/support/topic/customize-login-signup-modal-header-form/

Any update since to customize this?

If not, I have issues to change the #account-modal redirection, every time I land on the theme initial’s one and not to a customized new form / page. Can you help me either to :
1- change #account-modal link on “profile icon” click
2- change #account-modal associated page
