How can I tell which machines my license is activated on?

 Symptoms:

• I would like to know which machines I've activated my license on.
• I am receiving the error message 'Serial exceeds the maximum number of activations' but I don't know where the license is activated. 
• I want to find out what machines my Educational license is activated on.

Cause:

It can be difficult to keep track of where your licenses are activated, especially if you have a large team or use more than one device.

Resolution:

Unity license subscription holders are able to check their own activations via the My Seats section of their Unity ID account.
