And we will get the password
```
<script>
function login() {
let form = document.getElementById("login-form");
console.log(form.elements);
let username = form.elements["username"].value;
let password = form.elements["password"].value;
if (
username === "admin" &&
password === "Th1s_1s_4_L0ng_4nd_S3cur3_P4ssw0rd!"
) {
document.cookie = "login=1";
window.location.href = "/dashboard.html";
} else {
document.getElementById("error").innerHTML =
"INVALID USERNAME OR PASSWORD!";
}
}
</script>
</body>
