Hi,
I would like to buy and use your extension and I'd like to know if in case of subscription for a service there is a way to check and prevent users to share account password. So that I can be sure that one subscription is used just by one user.
I don't know if it can be done by IP address or just by device, like one user can register his devices and use his password only on those devices.
There are already a bunch of App and Website that allow you to prevent this big issue.
Thanks
