SQL Server 2014 Developer Edition Licensing?

SQL Server 2014 Developer Edition is now a free download for Visual Studio Dev Essentials members.

Lets say, I've registered for  Visual Studio Dev Essentials and downloaded the binaries. I've installed SQL server and provided access to 10 developers.

Questions: Do we need to register all those 10 developers with Visual Studio Dev Essentials  in order to be license compliant?

Thanks,

Michael.
