This is fairly difficult to do.

Do you want to prevent someone sharing a login? Or do you want to prevent
concurrent logins? The former is quite difficult to do - and it's a problem
that afflicts any authentication scheme, anyone can turn a private key into
a shared key. You could require users to use biometric identification or
similar, as that is difficult to share.
