Netflix on Tuesday expanded its crackdown on users sharing passwords with people beyond their immediate family as it seeks to shore up revenue at the leading streaming television service.
"A Netflix account is for use by one household," the company said in a statement.
Netflix said early this year that more than 100 million households were sharing accounts at the service, "impacting our ability to invest in great new TV and films."
Netflix has experimented in a few markets with "borrower" or "shared" accounts, in which subscribers can add extra users for a higher price or transfer viewing profiles to separate accounts.
On Tuesday, it announced it was expanding the policy to more than 100 countries including major markets such as the United States, Britain, France, Germany, Australia, Singapore, Mexico, and Brazil.
As growth at Netflix cooled last year, the Silicon Valley-based streaming giant set out to nudge people watching for free with shared passwords to begin paying for the service without alienating subscribers.
"This account sharing initiative helps us have a larger base of potential paying members and grow Netflix long term," co-chief executive Ted Sarandos said on an earnings call.
