Η Netflix today added a feature that allows you to set a four-digit PIN on your profile. New feature supposedly made to stop her access of children to adult content, but the real reason is different: to stop the friends you've given your account from messing with your profile.
Netflix friends who share their account with others will know that everyone who has access to their profile can see everything, what content they have seen, what the payment method is, not to mention that they can change their password owner.
Not anymore. You can adjust the PIN settings in “Profiles and parents data control”Of application settings. Set a PIN for your account and keep quiet until someone is found to break it :).
