**Description**  
I’ve been able to successfully integrate the zoom-sdk into my application. My application has multiple ‘rooms’ where users interact and use zoom for collaboration. I’ve multiple licensed zoom accounts to facilitate this. The documentation indicates that the jwt token that is used for authentication (in windows sdk) is a way for zoom to know who is using the application.

So, on a fundamental level, sans security considerations, can all instances of zoom-sdk that I invoke (on multiple pc’s) be authenticated with the same jwt?

My tests (in both cases, the meetings were successfully hosted/joined)  
a. 1 logged in user hosts and many non-logged in users join that meeting.  
b. 2 logged in users host different meetings and many non-logged in users join both meetings.

Questions-  
What I’m considering is to use different jwt tokens for each logged-in-user (host) and let all non-logged-in-users that join the meeting use the same token as the host. Is that allowed?

**Which App Type (OAuth / Chatbot / JWT / Webhook)?**  
JWT in windows-SDK

Almost, dev-bot. The first link was very helpful. This sounds good for the meeting hosts. As long as they are licensed in the same account, I can use the same sdk-app.

What about the non-logged in users? Will they also be able to use the same sdk-app key/secret?

It took me a couple of days to understand what the JWT is and what is being authenticated in this context. But that lead to the answer straightaway 🙂
