Letting the company to access purchased items from the asset store without using my login details?

I am working for a company and my contract is ending soon. The company paid for the Unity Pro license. When I leave this company, I won't be taking the license with me.

However, I registered the Unity Pro using my email address. I use this email address for forums, and purchasing things needed from the asset store.

The company paid for all things purchased in the Asset store for development purpose. At the end of my employment, I do not want my company to use my email address to access the asset store (as it is easily accessible from Unity).

What should I do in order to let the company to access all things purchased in the asset store without using my login details?
