Your named license needs to be assigned to an individual user.
If you have purchased the license, then by default the license is assigned to your account and you can log in to your Chaos product to use it. You are also the administrator of your my.chaos organization and you can add other users and assign a license to them. Then, the assignee will need to sign in with their Chaos account to use the product.
If you are part of another Chaos Organization where a license has been assigned to you, then you can log in with your Chaos account to use the product.
Floating licenses can be shared with everyone in your Chaos Organization by enabling the Floating License Sharing feature. Any member of the organization can access the available floating licenses after logging in with their Chaos account in the product.
You only need to login once with your account to access all of your Chaos products, regardless of license type. There is no need to maintain different licensing setups for named and floating licenses.
