Netflix began rolling out a new feature that allows users to assign an email address to individual profiles on a shared account, enabling independent sign-ins and separate verification codes. This is an optional feature, not a requirement — users can choose whether to set it up for their profiles. The change aims to improve account security and personalization while keeping the flexibility of shared accounts intact. Some households may find it useful for managing who accesses the account and receiving individual notifications, but it doesn't restrict how people currently share Netflix the way a mandatory email requirement would.
