I have managed to figure out how to pass credentials but I am really struggling with how to have the submit button invoke automatically. My dream is for the below code which is tied to a URL to pass the credentials to the webpage and enter with just the user clicking the URL link.

Is it possible?

Here is my code:

How can I get the submit to auto run?

My code is as follows:

div {padding-bottom: 10px;}
<form action="URL Link Here" method="post">
<input type="hidden" name="username" value="USER" />
<input type="hidden" name="password" value="GUEST"/>
<div><input type="submit" value="Guest Login" /></div>
