Amazon’s Prime Video is finally adding a feature that’s long since become a standard for streaming video services: user profiles. With profiles, Prime Video users will have access to their own Watchlist, personalized recommendations, and they’ll be able to track their own viewing progress, similar to rival services, like Netflix.

Customers can create up to 6 profiles for their household members, including 1 primary profile associated with the Amazon account, plus 5 additional profiles, which can be a mix of adult and kids’ profiles.
