Selenium: How to prompt user input and use the input value?

Question

I have a situation (during a selenium test), in which the user will receive a security code. The user must then input the security code before being allowed to continue.

Answer 1

It seems you have to accept and close the prompt first, before being able to store and use the value

    alert.accept();
    code = (String) js.executeScript("return window.promptResponse");
