How to upload a website that I created on the internet but it only be shown to people who have the exact link?

I made a portfolio for the University as an assignment, but there's some very sensitive information like my id number and my full name. I don't want any random person on the internet to stumble on it, I only want the professor to see it. So i want an exact link that is very hard so only people with this link can access my website. Is there some free website host for this exact thing? submitted by /u/W3-SD [link] [留言]
