I have simply form
<%= form_for @conn, Routes.register(@conn, :register), [as: :register], fn f -> %> <%= text_input f, :login %> <%= text_input f, :password %> <%= submit "SEND" %> <% end %>
I need put something to params, and read that value from controller, but it must be not visible/editable by user.
I know i can put hidden input, but it can be still edit by user (with browser/inspect element).
I have no idea how i can do this.
