If I pay for the engine, will my team be able to use it to?

So basically my team and I have been looking for an engine. If I pay the $19 a month will the rest of my team be able to access my work from a different computer with my payment, or do we all have to pay individually? And if we do how can I get them the game I am working on?

No, the license is per seat.

Details here:

But how will I be able to share the source?

Each team member signs in with a separate account, then project content and source is shared through source control:

If you want them to see it you can package then game and send it to them. If you want them to work in editor then they will need to pay 19$ individually at least for one month to get engine with editor (once you pay you can cancel subscription and stay at engine version you currently in, in general you need to pay once later you only pay for updates and marketplace access)

Ah okay. Thank you. I appreciate the responses and the help
