I am using Firefox as browser and use the browser-builtin functionality of saving the password and then going to the Create User page. Password field is representing by aspxTextBox control with Password property set to true. When submitting user creation I am asked by browser if I want to save the login credentials. It stores user email (field right above the password field) and password. But for login form we need userId, not email. How can I prevent (or customize) storing of password data on Create User page?
