Activation Code for other PC

Hello everyone, first of all I hope you are all having a great day.
I have a little problem. My friend is borrowing my Steinberg UR22C for a while. But he needs to install the cubase etc. and therefore needs an activation code. Can I find my old one back for any chance or is this a code that can be used only once? If so, can we get another activation code or do we need to come up with another solution?

An activation code can only be used once. You can move your license to other computers using the REACTIVATION procedure, but it can only be on one computer at a time. If you are going to be using Cubase on both computers, back and forth, etc., you will need another license for practical purposes.
