Assuming your two pages are on the same domain, you can use localStorage.

Popup.html:

var user = prompt('user name', '');
var password = prompt('password', '');
localStorage.user = user;
localStorage.password = password;

Then back in the main page:

var user = localStorage.user;
var password = localStorage.password;

Note 1: I won't comment on security (other than to say of course don't do it like I've done it above!)

Note 2: localStorage is only about 92% supported: http://caniuse.com/namevalue-storage

If Main.html has opened Popup.html with window.open(), then the Popup.html page can have a reference to its opening window (the window of Main.html) using window.opener. It could thus call a setCredentials callback function defined in Main.html using 

window.opener.setCredentials(...);

Example:

in Main.html:

// callback function called by the popup
function setCredentials(login, password) {
    // do what you want with the login and password
}

in Popup.html

// function called when the form is submitted
function login(login, password) {
    window.opener.setCredentials(login, password);
    window.close();
}

You can refer to the window that opened your new window (called the parent window) via window.parent and then execute your javascript using that object.

Here is an example of forcing a parent page to refresh using this: [1]Forcing parent page refresh through javascript

So in your case you could have say variables for username and password in your js like this and you could set them in the popup window like so:

//parent window
username = "";
password = "";

....

//popup window
window.parent.username = enteredUsername;
window.parent.password = enteredPassword;
