Its not a proper way to do it. You need a backend for that inorder to properly execute that. But if it just to play around you can have an alert box and just compare their value: if right it displays.

First, you have to add an id or a class to that inputs in order to select them within the script section. Afterward, you can select them and add any value you want. Such as:
<form>
<!-- user-id -->
<input id="user" type="text" />
<!-- user-password -->
<input id="pass" type="password" />
<button onclick="window.open('./index.html')">Enter</button>
</form>
<script>
document.getElementById("user").value = "UsernameOrId";
document.getElementById("pass").value = "SomePassword";
</script>
In order to compare, you should get the right password from somewhere like a database or some service, but since this is purely for learning purposes you can hardcode it in the script for checking. So, the final solution can be similar to this:
<body>
<form>
<!-- user-id -->
<input id="user" type="text" />
<!-- user-password -->
<input id="pass" type="password" />
<button id="btn">Enter</button>
</form>
<script>
const myPass = "SomePassword";
document.getElementById("user").value = "UsernameOrId"; // predefining the value simulating is saved and by default filled up
document.getElementById("pass").value = myPass; // predefining the value simulating is saved and by default filled up
const btn = document.getElementById("btn"); // getting the button to control its behavior on click event
btn.addEventListener("click", function () {
const passWhenClickingTheBtn = document.getElementById("pass").value;
if (myPass === passWhenClickingTheBtn) { // checking the value entered for pass
window.open("./index.html");
}
});
</script>
