Here is what Luxology has to say about it. I just looked. See what it says about dongle. LOL.

 

Thank you for purchasing modo.

The registration process for modo is only necessary if you purchased your product from a reseller. If you purchased your product via the Luxology on-line store, you can bypass this registration step and get your software and license directly from your account in the Registered Products section

There are 3 easy steps to get your modo software registered.

1. Create an account (or log in if you already have one).
2. Fill out the registration form.
3. Obtain your software and license from your account in the Registered Products section.

It's just that easy.

And remember, once you have registered your modo software, you can download modo and use it wherever you are and whenever you may need to re-install it. This means you can download modo if you want to use it at another location or if, for example, you purchased a new computer. There is no dongle (hardware key) needed for modo and we license modo to you—not to your computer.
