This is a test login page to demo the concept of how the professional organization (ISC2, IEEE, AMA, whatever) could securely certify their members' valid credentials. I'm using ISC2 as an example in what follows. It's really easy.

We assume the member can log in to the ISC2 site using his/her CISSP cert number and a password. Once there, ISC2 knows who it is and how long that cert is valid.

Let's assume you are CISSP cert number 990330 (we're not there yet, are we?) and your password is "naalipinpf" (short for:"Never Again Another Linkedin Post In The Public Forum"). Be a good boy or girl and enter those in the following login fields so we can keep playing (I already entered them for you):

(Yes, I know, sending the password as a get param is not such a great idea, but that isn't what this demo is all about.)
This page has no php in it, so you can see the entire source by simply doing "view source" in the browser.
