Trading computers

[ObsidianTeapot]

Could someone help me understand how accounts work when trading computers?

I have a friend who bought a new laptop. I'm assuming he has a steam linked FAF account because he's played on his new computer with no problems. He gave his old laptop to his friend who also had a steam linked FAF account. Unfortunately, when his friend tries to log in on the old laptop, it tells him that computer is already associated with a FAF account. That leaves me with the following questions.

How do you verify that a FAF account is linked to a Steam account?
Does linking your FAF account to Steam remove the UUID binding that apparently happens the first time you make an account?

If someone could help me be less confused I would really appreciate it.

Pretty sure it says that every user that is bound to a specific computer has to link his acc to steam in order to be able to log in. (as long as you use >1 faf acc on a pc)
If you get a pc from your friend make sure both of you have your FAF acc to your own steam acc. Then you'll have no problem.

PhilipJFry is correct.

To describe UID link more precisely:
UID link links a computer and a FAF account and means you cannot use any other FAF account on that computer.
However, if an account is linked to Steam, UID is ignored completely for this account.
