My pro license does not transfer to all instances of unity editor

I have been given a pro license which I have activated on my work laptop which is a Mac.

I want to be able to work from home as well and use Unity Pro on my Windows 10 laptop at home.

How do I use the same account to update my Unity Editor at home to pro?

Any help would be appreciated. Thanks

Just login with the same account and plug in the serial key on both instances.
