Session Key for Straming VOD?

We are trying to figure out how to create a single use stream key where only one user can use the key at a time. is this possible?
If not then users can simply copy the stream key and give it to their friends and watch the same video without having an account or pay for access…
We are suing signed URL’s but i can share the url with anyone and they can view the stream at the same time. Is there something im missing?

Yup, the reply we already got was “we’ll look into it”
