登录安全性Javascript

Question

下面的PassWord是非常有用的，然而，当我输入PassWords时，我怎样才能让它显示(*)，而不是显示实际的javascript？

function LogIn(){
loggedin=false;
username="";
password="";
username=prompt("UserName:","");
//username=username.toLowerCase();
password=prompt("PassWord:","");
//password=password.toLowerCase();

if (username=="User-1" && password=="PassWord-1") { 
loggedin=true;
window.location="https://site-1.com";
}

if (username=="User-2" && password=="PassWord-2") {
loggedin=true;
window.location="https://site-2.com";
}

//if (loggedin==false) {
if (loggedin===false) {
alert("OOPS!");
}
}

<div>
    <label for="pass">Password (8 characters minimum):</label>
    <input type="password" id="pass" name="password"
           minlength="8" required>
</div>
