Netflix to be logged on multiple devices, is that allowed?

We currently have the standard abo, means I can stream on 2 devices at the same time, is it ok for Netflix if you log on 5 devices? But do not stop streaming on all 5 at the same time?

Yes, if you are not watching at the same time, that's okay, but it must be your device so you can't share or lend your account, and so on

I do not have Netflix, but I think it's allowed! Just give it a try. If not just an error message

Why should not that be OK? Can you also log on 5000 devices, Netflix can only watch 2 at the same time.
