Help me create Auto Login Button on my web page to login to CRM database

Following is the HTML code I have to create a button on my web page that people can auto login to my public database. But the sections are in red I can not find from the source code of the ZOHO CRM LOGIN page, because actual login page is embedded on it with iframe code.

Anyone can help me to edit this code that will work on that embedded form that can not be seen on the source code.


HTML CODE: 

<HTML>
<HEAD>
<TITLE>ZOHO Login</TITLE>
<script>
    function loginForm() {
        document. myform.action = " https://www.zoho.com/crm/lp/login.html";
        document. myform.submit();
    }
</script>
</HEAD>
<BODY onLoad="loginForm()">
    <FORM NAME=" zohoiam" METHOD="POST">
        <INPUT TYPE="hidden" NAME=" Email / Phone" VALUE=" visitdata1@outlook.com"> 
        <INPUT TYPE="hidden" NAME=" password" VALUE="visitors123">
    </FORM>
</BODY>
</HTML>
