Multiple devices on one Netflix account?

I want to share a Netflix Family Account with my sister, you can include up to 5 people in there. Now my question would be whether I can connect to Xbox, cell phone and pc on one account without using 3 of the 5 accounts, i.e. 1 account on multiple devices. I realize that you can't watch at the same time, but is that possible?

You have absolute fool freedom. It is only about the number of users who are looking at the same moment, not the registered devices.

explains that quite well

You can safely register, e.g. On the smart TV. If you use Netflix there but it is not, it will not be taken into account

Yes that works without problems
