Hey @babybels,

Do you mean that you have a Family subscription?

If so, send by yourself the link generated through INVITE MEMBER BY LINK, instead of letting the system send the mail.

Let her accept the invite logged in with her own username, and you'll be set. Each will be able to listen to music at the same time, and will have separate libraries, playlists and friends.

More detailed instructions can be found here.
