Foto Abo for two devices

one is enough for use on an unlimited number if sevices (but for you only).

you can install the cc desktop app from here https://creative.adobe.com/products/creative-cloud on as many computers as you own and use it to install all (or some, if you want) of your cc subscription programs. the only (insignificant for internet connected computers) limitation is that you can sign-in (and therefore start your adobe programs) on, at most, two computers at any one time.  

because you can sign out from either (or both) signed-in computers using a 3rd computer, this could not (imo) be easier.
