Profile transfer enables the Netflix member and people using the member’s account to transfer a profile to a new account, an existing account, or an extra member slot – including the recommendations, viewing history, My List, game saves, settings, and more.
The profile transfer feature is included with your account. If you don’t want to allow this feature on your account, you can turn off profile transfers by following the instructions below.
A profile can be transferred as long as it:
is on an active account
isn't a Kids profile
isn't PIN protected (if it has a PIN, remove it and then transfer)
doesn't have a profile email address attached to it
